Chelsea defender Gary Cahill has hailed the impact of their Spanish pair Cesc Fabregas and Diego Costa this season.

The pair joined Chelsea last summer.

"Diego has come in and although he hardly speaks any English, had never played in this league before and has never lived in this country, he had an impact from the word go," Cahill told the Mail on Sunday.

"Time and again players come over and take a long time to settle down and get into the groove of the Premier League but it hasn't fazed him. He's one of the liveliest jokers in the changing room. He's certainly entertaining and he has settled into the group really well.

"With Cesc, everyone knew his quality and he has played in this League before so in a way it was easy for him to come back. But still, he has come into the side like he has never been away and the connection Costa and Fabregas have had this season has been fantastic for us."
