After five years at Liverpool, Xabi Alonso opted for a fresh challenge and joined Real Madrid in a £30million move in 2009.
Alonso, who had fallen out with Liverpool boss Rafa Benitez, was one of eight first-team signings that Madrid made during that summer.
The midfielder went straight into the starting Xl and made his debut against Deportivo La Coruna on the opening day of the La Liga season, helping Real to a 3-2 win.
He went on to win a La Liga title, the Champions League and two Copas del Rey at Madrid, but we’re asking you to name the Xl from his debut.
If you’re looking for another challenge after this, why not have a go at naming the 25 players Real Madrid have signed from the Premier League?
