Manchester United boss Ole Gunnar Solskjaer was left frustrated after defeat to Manchester City in the Carabao Cup semifinal.
Second-half goals from John Stones and Fernandinho secured their progress as City cut loose after a first period in which both sides had goals disallowed.
Solskjaer lamented both City goals, saying: "Manchester City can score many great goals. You can accept that. When you concede two simple set-plays, it's very disappointing. Just not good enough in those moments.
"We didn't create enough big chances. They didn't either. We didn't have the extra finesse we've had in the games lately. We weren't good enough today.
"We played against a very good Manchester City team. They played well. When they play well you have to play very well to beat them. We were just lacking that little bit.
"We're getting closer. This is a much better version of United than a year ago in those semis.
"It's not psychological [losing in four semis]. Sometimes you meet good teams in the semis. We met, at the moment, City are probably the best team in England."
