Guus Hiddink is interim manager of Chelsea but Mikel John Obi has voiced support for having him remain long-term.

The improved form of Diego Costa and Cesc Fabregas are examples of Hiddink's influence.

“From day one, since Guus has come in, the atmosphere has changed,” Mikel said. “The players feel more relaxed, people know what their jobs are and people are getting on with their jobs in a more relaxed way. And in a way they can perform very well. He has given responsibility to people and expects them to thrive on it and make sure they do it in way where they feel comfortable. I think that is what the players are showing now.”

Mikel added: “You can see Diego. It takes a lot to get Diego in a good mood.”
