Chelsea defender Levi Colwill has revealed manager Mauricio Pochettino was furious at halftime of their FA Cup win against Preston.

The Blues won 4-0, though the score was 0-0 at halftime.

Asked if Pochettino turned on the hairdryer at half-time, Colwill told ESPN: "Something like that!

"I think we needed it though, we weren't good enough, as everyone saw.

"The second half was much better."

Colwill added: "Raheem (Sterling) normally practises free-kicks the day before a game and he always scores.

"I think he's scored two now — Newcastle and then today — so from that position, he's a specialist at free-kicks.

"I love playing with Armando, he's a great striker and a good mate of mine.

"I always encourage him because I know how good he can be. Today he showed it with his goal."
