Chelsea boss Graham Potter admits Thiago Silva was lucky to avoid a red card in victory at Crystal Palace.

In the first half when Chelsea were already behind to Odsonne Edouard's opener, the 38-year-old Brazilian was caught on the ball and went to ground, deliberately handling the ball to stop Palace's Jordan Ayew breaking away clean through on goal.

The centre-back was shown a yellow card by referee Chris Kavanagh, and although a VAR review followed, Silva's punishment went no further, much to the frustration of Palace manager Patrick Vieira.

Potter said: "I thought it was touch and go. The fact he was quite far from the goal saved him and it could've gone the other way. It's a close one, I can understand Patrick's frustration. It's a 50-50 one."
