Manchester United host Aston Villa on Saturday and the Reds will be looking to continue their sublime form after back-to-back wins over Tottenham and Liverpool.
Louis van Gaal's side are in fourth place in the Premier League table, a point behind Arsenal and five points ahead of arch rivals Liverpool - who sit in fifth position.
However, Arsenal legend Merson heaped praise on the Red Devils’ performance at Anfield and has backed them to seal a win over Villa at Old Trafford.
"I have to give credit where credit is due, Manchester United were absolutely outstanding against Liverpool," the former England international told Sky Sports.
"They gave Brendan Rodgers’ side the run around at Anfield and the home side were never in the match. That was testament to United’s performance and I’m backing them to keep that level up at home to Aston Villa.
"Tim Sherwood’s men had a bad result against Swansea when the expectation was on them to win and despite the pressure being off when they make the trip to Old Trafford, I can’t see them getting anything."
Paul Merson Predicted: Man Utd 2-1 Atson Villa.
