United scored 4 first half goals before Gray pulled one back in the second half to level things up.
Speaking after the game, Claudio Ranieri said:
“It is not possible to concede three goals from corners. That means you are not concentrating, We are usually very solid at corners and free-kicks, it was very strange. Until now we have been very strong, we have made some mistakes. I can understand that they score with headers, that they are very tall, but to score a smart goal from a corner is not possible.
“It is important to clean our mind and get ready for the Champions League on Tuesday.”
