Alonso was regarded as a quiet and friendly person by his former teammates at Liverpool. He is married to Nagore Aranburu and the couple have three children: Jontxu, Ane and Emma. Alonso stayed in Merseyside to be at her side while she gave birth, later saying, “It was a little frustrating to miss the match against Inter but I have to be with my family at times like these.” His decision to place his family ahead of a Champions League tie caused much friction with former manager Rafael Benítez. On 30 March 2010, they had their second child, a girl named Ane Alonso Aranburu. Their third child and second daughter, Emma Alonso Aranburu, was born on 2 December 2013. Alonso and former Arsenal player Mikel Arteta were neighbours on the same street while growing up in San Sebastián and also lived near each other in Liverpool. Alonso convinced Arteta to transfer to Everton after he told him how happy he was living in Liverpool. Alonso also helped persuade former Real Sociedad teammate Juan Ugarte to make a move to Wales by joining Wrexham in 2004. Alonso’s brother Mikel plays for Spanish club Real Unión. He previously spent a season on loan at Bolton Wanderers in the 2007–08 season with an option for a permanent deal. However, the team opted not to extend the loan deal and he returned to Spain to train with Xabi Alonso’s former club, Real Sociedad. Alonso also has another brother involved in football, Jon, who works as a referee. Alonso is a Meath Gaelic football supporter. His interest in the Irish sport stems from the age of 15 when he went to the Irish town of Kells, County Meath, and stayed with a family to learn English, where he played it in his spare time. Even while playing at Real Madrid, Alonso has declared himself a Liverpool supporter and returns to watch games at Anfield when his schedule allows. He was quoted in The Times Online in 2011 as saying, “I am still a Liverpool fan and will be forever, absolutely” and that he will raise his Liverpool-born son as a Red supporter.
