Chelsea left back Ben Chilwell is not afraid of competition at the club.

The big money summer signing has been forced to rotate with Marcos Alonso since the arrival of manager Thomas Tuchel to replace Frank Lampard midseason.

Despite not always starting, Chilwell has worked his way into Tuchel's plans, and showed his importance with a vital goal in the Champions League quarter final first leg against FC Porto.

"When the manager came in it was a clean slate for everyone," Chilwell told reporters ahead of the second leg, per the club website.

"I didn't play the first three or four games which could have got me down, but I used it as an opportunity to work harder, and ask the manager questions in training about where he thought I could improve my game to get more game time.

"When I get the opportunity to play I want to prove to him I should be playing more regularly. I'm sure the other players, Marcos included, are doing the same thing."

Chilwell added: "That competition is very healthy.

"With the stage of the season we are at, with quarter-finals and semi-finals in the cups, and our league positioning trying to finish in the top four, it's very important we have everyone in the squad challenging each other for 11 shirts, training hard and playing hard because they want to be in the team."
