Potter disappointed with Man Utd draw
has said he is disappointed after a 1-1 draw with Manchester United on Saturday.
The Blues thought they had taken three points after Jorginho converted a penalty in the second half.
But Casemiro’s looping header crossed the line, to ensure both sides finished with one point apiece.
Potter, speaking to Sky Sports, said: “It’s disappointing because we’re 1-0 ahead at the end but over the course of the game a point is about right and I’m not sure if we did enough to win it.
“A really fighting performance from us, we improved a lot after 30 minutes so we will take what we get.
“We couldn’t get enough control of the game in the middle. The boys gave everything they can and improved a lot in terms of our work, but we were playing a good side.
“I thought the players’ attitude on the pitch was great, the boys gave everything in a hard, intense match in the middle of a really busy period. The boys left everything out there.
“Kepa was a bit unlucky but it’s only just gone in and the first goal we have conceded in a while but we have to take the positives. I thought we could’ve attacked a bit better at times. We had chances, they had chances so a point is about right.”
