The Reds showed plenty of attacking intent as they played out a thrilling 3-3 draw with Arsenal in midweek but Jurgen Klopp will be concerned by his side’s shaky defence.
United, meanwhile, also warmed up for their trip to Merseyside with a 3-3 draw as they conceded a late equaliser and were forced to settle for a point against Newcastle United at St James’ Park on Tuesday.
Liverpool will be eager to return to winning ways in the Premier League after a string of disappointing results since the turn of the year.
United will also be out to close the gap on fourth-placed Tottenham Hotspur.
But former Liverpool man Lawrenson feels that both sides are likely to have to settle for a point from Sunday’s clash.
Lawrenson told BBC Sport: “Liverpool came back extremely well to draw with Arsenal on Wednesday. I was at Anfield and what was interesting was that Jurgen Klopp’s side took the lead twice, and were really good for 25 minutes when they played their pressing game.
“But they cannot sustain that at such a high tempo for 90 minutes and, as we saw against the Gunners, when they tail off against a really good side, then the opposition come back into it.
“So, I never thought they were in control of the game against Arsenal and it is likely to be the same against Manchester United, who will have an extra day of rest. That might affect Liverpool’s ability to press, which would definitely help United.
“I don’t see United playing as open as they did against Newcastle at Anfield, though. Louis van Gaal’s side will come and sit and look to hit Liverpool on the break. Van Gaal is under a bit of pressure, but I don’t think his side will lose.
“Everyone has been writing Wayne Rooney off but he has shown in the past three games that he is still the best player they have got, even if his legs are not what they were.”
Liverpool are currently ninth in the table.
