Manchester United boss Erik ten Hag admitted mixed emotions after their 2-2 draw with Liverpool.
After fighting back from a goal down to lead 2-1, the Reds leveled via a Mohamed Salah penalty.
Ten Hag said: "Very mixed emotions.
"On one side I am disappointed that we have dropped seven points in one week after being in winning positions, but we have to blame ourselves for making stupid mistakes.
"On the other side I am very proud.
"You see how we are improving and the potential of this squad is amazing - I am proud.
"In decisive areas we were losing battles especially with young players we were not confident to win them [duels].
"We encouraged in the second half to do better and they stepped up."
On their confidence, he added: "It's two things.
"One thing is physical after Thursday, a big intense game, and then return from London dealing with the frustration. On the other side is the belief that you can win such duels."
