Alejandro Domínguez (footballer, born 1981)

2.1. River Plate (First Spell)

After his initial professional steps at Quilmes, Domínguez joined River Plate, one of Argentina's most prestigious clubs, often referred to as "The Millionaires". During his formative years at River Plate, he played a crucial role in the team's success, winning the Clausura three consecutive times in 2002, 2003, and 2004.

2.2. Rubin Kazan (First Spell)

Domínguez's talent attracted the attention of several European clubs, and in 2004, he made the move to Russia, signing with Rubin Kazan. He quickly adapted to Russian football, and by 2006, he was a key player. During the 2006 pre-season, Rubin Kazan considered selling him but ultimately decided to keep him as offers did not meet their valuation. During this period, he also contributed to Rubin Kazan's victories in the Copa La Manga in both 2005 and 2006. His impressive performances led to him being named the Sport-Express Top Foreign Player in the Russian Premier League for 2006.

2.3. Zenit Saint Petersburg

Before the start of the 2007 Russian season, Domínguez made a high-profile transfer to Zenit Saint Petersburg for a fee of 7.00 M EUR. This transfer fee set a new record within the Russian Premier League at the time, though it was later surpassed in 2008 when Danny moved to Zenit for over 30.00 M EUR.

Domínguez played a significant role in Zenit's success, often operating as a right winger. One of his most memorable performances came in the UEFA Cup semi-final against Bayern Munich, where he provided two assists in a dominant 4-0 victory that sent Zenit to their first-ever UEFA Cup final. Zenit went on to win the UEFA Cup and the UEFA Super Cup.

He was also instrumental in Zenit's first domestic championship title in 2007. In a critical match against now-defunct Saturn, with Zenit leading 1-0 and needing a win to secure the title, Domínguez made a miraculous last-minute save. As the Gazprom-sponsored side's defense hesitated on a corner kick, Domínguez, despite being one of the shortest players on the pitch at 5 in, leaped to head Baffour Gyan's shot onto the crossbar, preserving the lead and securing the championship.

2.4. Rubin Kazan (Second Spell)

On 13 March 2009, Domínguez returned to Rubin Kazan from Zenit, reportedly due to problems with Zenit's coach, Dick Advocaat. In his second spell, he continued to impress, playing as a center-forward and attacking midfielder. During the 2009 season, he scored six consecutive goals from penalties, contributing significantly to Rubin Kazan's league triumph.

In the 2009-10 UEFA Champions League, Domínguez delivered strong performances, scoring goals against Inter Milan and FC Dynamo Kyiv. He also provided a crucial assist to Gökdeniz Karadeniz, who scored a stunning match-winning goal against FC Barcelona during the group stage. Despite his efforts, Rubin Kazan failed to advance to the knockout round after a 0-2 loss to Inter Milan. His outstanding form in 2009 earned him the title of Best Footballer in Russia, as recognized by the Russian Football Union, Sport Express newspaper, and the Russian weekly magazine Futbol.

2.5. Valencia CF

On 11 December 2009, it was announced that Domínguez would join Spanish club Valencia. He officially signed a three-and-a-half-year contract on 14 December 2009. During his time at Valencia, he faced competition for a starting spot, often being behind players like Roberto Soldado and Aritz Aduriz. He also reportedly dealt with injuries, which limited his impact. In May 2011, he expressed frustration with the club's objectives, implying they prioritized UEFA Champions League qualification over a league title. There was speculation in the middle of the 2010-11 season that Juventus was interested in a loan deal with an option for a permanent move; it was confirmed that Domínguez held an Italian passport, making him eligible for such a transfer without affecting non-EU quotas.

2.6. River Plate (Loan)

In mid-2011, Domínguez took a significant step by contacting his employers at Valencia to negotiate a loan move back to his former club, River Plate. This move was particularly notable as River Plate had, for the first time in its history, been relegated to the second division of Argentina, the Primera B Nacional. His decision to return and help his boyhood club was highly appreciated by the fans.

During his loan spell, Domínguez became one of the team's key figures, playing both as an attacking midfielder and a forward. He scored 5 goals and provided numerous assists, also serving as vice-captain. His vital contributions were instrumental in River Plate's successful promotion back to the top division after just one season. However, despite his efforts, he was informed in late June 2012 that he would not continue at River Plate, as the club decided not to negotiate his permanent transfer from Valencia. He departed alongside top scorer and former captain Fernando Cavenaghi, with both players citing irreconcilable differences with club president Daniel Passarella.

2.7. Rayo Vallecano (First Spell)

After leaving Valencia and River Plate, Domínguez signed a one-year deal with Spanish Primera División club Rayo Vallecano in early August 2012. He stated that he was attracted by the project presented by the club, and also by the red stripe on Rayo's white home shirt, which reminded him of his beloved River Plate's kit.

2.8. Olympiacos

In July 2013, the 32-year-old Argentine opted to join Greek side Olympiacos, signing a two-year contract under former Getafe and Sevilla boss Michel. On 1 December 2013, he scored his first goal for the club in a 3-0 home win against Ergotelis in the Super League Greece.

Domínguez made a significant impact in European competitions. On 26 February 2014, he scored a goal against Manchester United in the first leg of their UEFA Champions League last-16 tie, expressing immense satisfaction with the team's performance and victory. He impressed again on 13 September 2014, scoring a spectacular goal in a 3-0 home win against OFI. He also delivered a strong performance in Olympiacos' 3-2 home win against Atlético Madrid in the Champions League, earning a spot in the Champions League "Team of the Week." On 9 December 2014, he scored another impressive goal in a 4-2 home win against Malmö in the Champions League.

On 2 April 2015, Domínguez, an indispensable member of the Olympiacos squad, signed a new contract until 2017. Despite receiving offers from Argentina, he chose to remain at Olympiacos, citing his happiness with life in Greece and his enjoyment of playing for a club that consistently competes for titles. In the 2014-15 season, Olympiacos won the league, with Domínguez scoring 15 goals (the third-highest in the league) and providing 11 assists (the highest in the league). On 23 May 2015, he scored a stunning curling effort in a 3-1 victory against Skoda Xanthi at the Olympic Stadium, helping Olympiacos secure their 27th Greek Cup triumph.

For the 2015-16 season, Domínguez scored his first goal on 12 September 2015 in a 3-1 home win against Platanias. On 13 December 2015, his lone goal secured Olympiacos' 14th consecutive Super League Greece victory, setting a new club record, against Panetolikos. He also scored on 3 January 2016 in a 3-1 away win against Panionios. On 18 February 2016, during a UEFA Europa League round of 32 match against RSC Anderlecht, Domínguez made his 100th appearance for Olympiacos. On 25 August 2016, in a crucial Europa League playoff second leg, he came on as a late substitute and scored the first goal in extra time, leading his club to a 2-1 home win (3-1 on aggregate) against Portuguese club Arouca.

By mid-November 2016, Olympiacos manager Paulo Bento did not consistently include Domínguez in his first-team plans. However, Domínguez maintained a professional attitude in training and remained committed to seeing out his contract. His positive influence on the team's offensive efficacy, even as a late-game substitute, was evident in matches such as the 3-1 comeback victory against Panetolikos on 18 December 2016. In April 2017, under new coach Takis Lemonis, Domínguez gradually returned to the starting squad and concluded the season with an away goal in a 2-0 win against Panetolikos, contributing to Olympiacos' fourth consecutive Super League title.

2.9. Rayo Vallecano (Second Spell)

On 7 August 2017, Rayo Vallecano confirmed the return of Domínguez to the club for the latter part of his playing career. He contributed to Rayo Vallecano's success during this period.
