Chelsea fullback Ben Chilwell admits their 0-0 draw with Tottenham on Sunday was tense.

Chilwell insists a clean sheet was a positive for the Blues.

He said, "The game was on a knife-edge. I think both sides were tactically pretty good so we're happy with the clean sheet.

"When you've got a strikeforce like they have, we as defenders have to concentrate for the whole 90 minutes and the clean sheet was very important.

"Points are crucial and neither team wanted to give the other side any points. We'd have loved to win the game at Stamford Bridge against our rivals but we needed to keep a clean sheet."
