Diego Costa has heaped praise on Chelsea boss Jose Mourinho for his ability to work out his opponent's flaws.
The Spanish striker joined the Blues from Atletico Madrid for £32million in the summer and insists he has learnt a lot more working with the Portuguese than he has with any other manager.
"We all know that he's among the best managers in the world," said Costa.
"When you arrive in a team with a manager like him, you try to spot every single thing you can learn from him.
"Every manager has a different way of reading the game.
"In regards to Jose Mourinho, he is a clever manager who spots very well the opponent's virtues and weaknesses. Our training sessions are based on that."
