Reports suggest United may propose a swap deal to acquire Nigerian striker Victor Osimhen, currently on loan at Galatasaray, in exchange for Rashford. With a release clause of £62 million ($77m), Osimhen would be an expensive addition, but United hope to reduce the financial burden by including Rashford in the negotiation.
Shearer, however, remains sceptical as he believes that such a transaction will be highly complex and challenging to execute in the January window.
"There have been reports about a swap deal with Napoli for Rashford with Victor Osimhen going to Old Trafford. We’ve seen other players go to Serie A and get their careers going. However, I think that where Marcus is concerned, he’d have to look at every option - to see whether one fits or suits him, as well as Manchester United, which is perhaps the bigger consideration," he said.
"Whether that can be done in the next month or so, or whether he’s going to try and force his way back into the Man Utd starting eleven, I don’t know. I do get the idea that it would be very difficult to get a deal done, because of all the different angles and parties involved with the deal. I do think that it will be difficult to get a deal done this January, regardless of a loan or a permanent deal. It's a really difficult transfer to do. There’s a lot to do and so many aspects to a transfer. First of all, it’s about agreeing on a fee, secondly, agreeing to a salary - he’s on a huge wage right now at Man Utd and I’d be amazed if somebody in the Premier League would be willing to match that."
