Chelsea skipper John Terry admits he loved seeing Michael Ballack and Didier Drogba rowing during last season's victory over Manchester United at Stamford Bridge.
"He told me that when he came back he wanted to be right and fully fit and that is what he has done. What impresses me is he has been there and done it. He has scored a lot of goals, has a lot of experience in major competitions and loves the pressure of big games.
"When we got that penalty against United, he was the one saying, 'Give me the ball'. He wanted the responsibility and you thrive alongside people like that. I didn't even mind when he had a row with Didier Drogba about a free-kick.
"They work on free-kicks in training, both fancy their chances so both want to take it. They can say what they like to each other on the field as long as they shake hands in the dressing room."
