The former Spurs man has been an important player since arriving at the Bernabeu in 2013, lifting two Champions Leagues and even scoring in the final in Lisbon.

Six wins, six draws and two defeats: a percentage of victories of 65,4% when the Cardiff Express is on the team. Without the winger, 22 out of 28 matches have favoured Madrid, with four draws and two defeats taking the winning percentage up to 79%.
