Liverpool legend Jamie Carragher believes they froze at Manchester United for Sunday's 1-1 draw.
Jurgen Klopp's Reds needed a late Adam Lallana equaliser to rescue a point at Old Trafford after Marcus Rashford's first-half goal looked to have earned a deserved victory for the struggling Red Devils.
Speaking during the game, Carragher told Sky Sports: "I always talk about Everton having almost a mental block when they come to Anfield, and watching Liverpool here, it's almost like it's a mental block.
"It's not the same team you usually watch.
"I said before the game, United away is always a tough game and you can lose it but it's the performance more than the scoreline that is the biggest worry for Liverpool. Every time they come to Old Trafford, it is the same problems."
He added: "I think Liverpool will be delighted. It's very difficult for any team to come to Old Trafford, it's a derby game and their record is not great here.
"It almost feel like certain Liverpool players have a mental block when they come here so to get out with one point, considering how they performed, I think Klopp will be pleased."
