“You just don’t know what you’re going to get with Manchester United,” Paul Merson told Sportskeeda.
“They were so fortunate against Norwich City and were never going to beat Newcastle United away from home, so this will once again be a hard game for them.
“They’ll beat Burnley and Wolves and people will say their manager is unreal and all that, but based on what I’ve seen so far, I don’t see them finishing in the top four.
“Manchester United are a long way off now and if they somehow manage to get to fourth, it’ll be a great season for them.”
The former Arsenal man added: “In terms of their team, I strongly believe Cristiano Ronaldo should be left out [against Wolves].
“It won’t happen, but Edinson Cavani should take his place up front with the likes of Jadon Sancho, Marcus Rashford, and Mason Greenwood in contention to play on the wings.
“Something’s just not right there. I think there is a lot going on behind the scenes and it doesn’t look good for them. That said, they’ll probably win this one, but it won’t be pretty.”
United are unbeaten under Ralf Rangnick so far and could get closer to the top four spots with a win on Monday.
The Red Devils are currently seventh in the Premier League standings, just two points behind sixth-placed Tottenham.
