That’s according to United legend Gary Paillister, who played along side Ole Gunnar Solskjaer at Old Trafford.
Lukaku left Manchester United on Deadline Day for Inter Milan after the Italian club coughed up nearly all the money the Red Devils paid for him back in 2017.
Inter paid £73milliom, just £2m short of what United had to give to Everton in exchange for the Belgian’s services.
Lukaku reportedly wasn’t happy with life at United and it’s been said that Solskjaer made the striker clear of his plans to anoint Marcus Rashford as first-choice striker.
But Pallister believes his ex-team-mate had another United player on his mind – Mason Greenwood, when he made the decision to sell Lukaku.
“I think they have Greenwood coming through, and he looks a special talent,” he told American Gambler.
“You don’t like to get ahead of yourself with kids of that age, but it’s been a while since I’ve seen anyone be that comfortable in that environment at that age.
“He’s six foot odd, can use both left and right feet, knows how to score a goal and he looks the real deal at the moment.
“He’s still got a lot of work to do, he has to mature and find his feet at that level.
“The fact that Ole has played him a lot in pre-season, and had him on the bench on the weekend suggests he’s ready for the Premier League.”
Pallister then suggested that Lukaku was overweight and not suited to how Solskjaer wants United to play their football.
Lukaku, however, was United’s top scorer last season, but Pallister thinks Solskjaer prefers a more complete player to lead his line.
“I think Lukaku is a goal scorer and he will score plenty of goals, but the way they want to play at times, he’s too heavy,” he added.
“You look at the pace in the present game; maybe Ole is looking at that and saying he can’t implement that into his game for me. He was surplus to requirements.
“He’s a goal scorer, an instinctive goal scorer. He’s not the most clinical but he will get you 15-20 goals a season, but we were looking for a more rounded player.
“He plays Lingard, Martial and Rashford, and we caught Chelsea napping on the ball high up the pitch. So when you can do that you’ll have more space to go into and score more goals.”
