Alonso with Barcelona in 2018
|Born||December 4, 1975|
|2005–2008||Joventut Badalona (assistant)|
|Career highlights and awards|
Alonso made his coaching debut in the Liga Endesa (Spanish League) in 2008, with Joventut Badalona, a team where he had previously worked as an assistant coach. He was sacked by the club in March 2010, after his team's poor results in the Spanish national domestic league and in European-wide competition.
In 2011, Alonso once again became a head coach in the Liga ACB, thanks to his signing of a new contract with Lagun Aro GBC. He left GBC in 2014, in order to sign with the Spanish club Bilbao Basket.
In July 2016, he parted ways with Bilbao Basket, and he signed a two-year deal with Baskonia. Despite reaching the EuroLeague playoffs, Alonso and Baskonia split up after being eliminated by Valencia Basket in the semifinals of the domestic league play-offs. Consequently, he signed a two-year contract with an optional third with FC Barcelona Lassa. On February 5, 2018, FC Barcelona part ways with him.
Spanish national team
In the summer of 2013, Alonso was the head coach of the Spanish Under-20 junior national team, and he coached them to the bronze medal at the 2013 FIBA Europe Under-20 Championship, which was played in Tallinn, Estonia. He was also an assistant coach with the senior Spanish national team at the 2014 FIBA World Cup.
