Thomas Tuchel believes he was unfair to Kurt Zouma when he arrived at the club in January.
The German coach took charges of the Blues in January and he hardly Zouma in the regular team since January who was a regular under Frank Lampard.
Tuchel chose Rudiger instead who has impressed for the Blues this season and would likely be handed a new contract in the summer.
‘Nothing is better than what he’s doing to fight for a new contract,’ said Tuchel. ‘If he wants to have a new contract he has our full support, if he wants to stay at the club then speaking with performances, this is what he’s doing.
‘Since day one we chose him in the first match, it was an unfair decision against Kurt, but he is German and I had a clear picture of what he can do because I followed him a bit more than Kurt Zouma.
‘So it was an unfair decision and I had a clear picture of what I can ask of him and what he is capable of delivering to a team.
‘He took the chance and since then it is absolutely well deserved that he is in the team.
‘He is kind of an aggressive leader, has a natural aggression in him, hates to lose, hard to beat in duals, very very brave and full of energy in defending.
‘He’s leading by example, has a positive aggression, this is what we like and when he can channel all this into top performances we are very happy to have him.’
