The Red Devils have endured a disappointing end to the campaign and they have missed out on a top-four finish in the Premier League under Ole Gunnar Solskjaer.
Manchester United have struggled to find consistent form all season and they currently find themselves in sixth place in the table and having won just one of their last five outings in the top flight.
With nothing but pride left to play for, the Red Devils will welcome Cardiff City to Old Trafford on Sunday as they look to end the season on a positive note.
And former Liverpool FC star Lawrenson is backing the Red Devils to claim a comfortable victory in front of their home fans on Sunday afternoon.
Writing in his column for BBC Sport, Lawrenson said: “Manchester United are facing a huge summer in terms of which players stay or leave the club.
“It would be a huge job for a seasoned manager, let alone Ole Gunnar Solskjaer, who does not have much experience but will stand or fall by what he decides over those ins and outs.
“In terms of the game, well, Cardiff will have a bit of a go but United should beat them.
“But there is nothing riding on the result – it is what happens next that is important, and the same applies to the Bluebirds.
“I think their hopes of making an instant return to the top flight rely on whether Neil Warnock stays on when his contract ends, which is after this game.
“Warnock has an outstanding record in the Championship and he does not have to spend fortunes to get his teams up.
“If he is still in charge next season, I think they will be very competitive, if he is not, then I would not be too sure about where they will finish.”
Manchester United will likely be linked with a host of players this summer as they look to try and revamp their squad ahead of next season.
The Red Devils have now ended the second season in a row without winning a trophy, after their Europa League and League Cup triumphs under Jose Mourinho in 2017.
