Vedran Corluka admits Tottenham and Croatia teammate Luka Modric was doubting himself earlier this season.
Corluka said: "He was disappointed like every other player here. He thought, 'My God, I'm worth 20million Euros. I need to show something that I am not showing'.
"It was a hard time for him but now he is playing well - and the team is starting to play well - it is much easier for him. Now his mood is excellent."
