Xabi Alonso is 32 years old and he'll be playing this 2014 World Cup for Spain. He won the 2010 World Cup and the 2008 and 2012 UEFA Eurocup. And now, Real Madrid want him to leave the Spanish national squad after this summer and focus on the club, according to Marca.
This is a common thing in England, where Ferdinand, Terry or Cole have left the three lions as well. Xabi Alonso still has two years left on his contract with Real Madrid, and if he leaves the Spanish squad he could make the best of his time remaining with los blancos.
This decision could certainly help Alonso's career with Real Madrid, as the FIFA breaks are often really busy and harm the clubs the game after. Xabi Alonso has played well this season but he could definitely use some rest during the season. Furthermore, he will likely need to rotate a bit next year.
