Manchester United boss Erik ten Hag believes that consistency is their main issue.
The Red Devils have lost six of their last ten games in all competitions this season.
While the Dutch coach believes there are some positives to take from all those games, he admits his side is not good enough in the big moments.
He told reporters: "Consistency. That is the problem we are struggling with. In parts of the games, in big parts, we do a lot of things right, but we have moments where we struggle and in such moments we can't survive.
We need to do the right things, be consistent and do it like before, so definitely you can mark such a moment like when we score or concede a goal. We have to step up."
On fixing these issues, he added: "It's difficult, but you do research and look at it. We've spoken about it, how we can improve and we we make some agreements about that. I think it's more than one factor, concentrations is one, but there's other things."
