Salomon Kalou has hailed the impact at Chelsea of Roberto di Matteo since his appointment.

Kalou says Di Matteo has brought the Blues squad together and believes he deserves a huge amount of credit for his work over the last two months.

"We have to give credit to Robbie - he has brought energy to the team and the club," said the Ivorian.

"He gave belief to the players who were not in the squad before, and he gave chances to other players.

"When you want to win competitions you have to cope with every member of the squad, and include all the players. That is what he has done well. He has brought everyone together and that is a credit to him."
