Manchester United have been urged to sign Bayern Munich striker Robert Lewandowski by former defender Clayton Blackmore.
“They need to get a top striker who the players can learn from,” Blackmore told the Daily Star.
“I’d like to see Bayern Munich’s Robert Lewandowski come in. He’s 31 although still scores goals for fun.
“I’d also be happy if Zlatan Ibrahimovic came back.
“We got rid of Romelu Lukaku to Inter and that was a big decision. For me, Solskjaer now has to replace him.
"He should have replaced him in the summer and Lukaku probably shouldn't have been sold if we didn't have someone lined up.
“We need a top striker who's going to help out the kids.”
“The young lads have shown what they can do when they're on form, but I think if they had a bit of experience up there they'd be a lot better.”
Blackmore was also critical of Solskjaer’s decision to let defender Chris Smalling leave on loan and instead allow Phil Jones to remain at the club.
“If you'd given me a choice between Jones and Chris Smalling, I'd always take Smalling,” he added.
“Jones has got to up his game if he wants to stay at United. He's got to start making the correct decisions, at the right time.
“To be fair to Jones he gives you 100 per cent - although it's probably too much. He needs to learn to read the game and get in the right positions. There's still too many last ditch challenges.
“I’d also put Smalling ahead of Marcos Rojo and Eric Bailly.
“I’d have definitely kept him at the club. He's tall, he's quick and when he's confident he's as good as anyone,” added Blackmore. “I don't think it's the end of the road for him.
“They still haven't got the right combination at the moment. Victor Lindelof is okay, but he’s not dominant enough in the air which is such a key thing.
"I thought Smalling would have been one of the main centre-backs this year along with Harry Maguire and Lindelof.”
