Marcus Rashford scored his side's only goal during the 1-1 draw with leaders Liverpool on Sunday and his performance provoked a heated discussion in the Sky Sports studios about United's needs up front.

But as Gary Neville and Graeme Souness argued over Rashford's suitability, the decision to let Romelu Lukaku go and possible transfer targets, the solution for Roy Keane was simple.

"Just go and get [Harry] Kane from Tottenham," he said. "Easy. They are in disarray. Just go and get him."

Souness said of Rashford's potential to be a star: "He might be one day, but he's not the finished article right now. He's not scored enough goals in the Premier League for Manchester United to hang their hat on him being the man that's going to take them back to where they want. He needs help.

"He has everything to be a player, but this year he has been asked to be the main man. It's the hardest position to play on the football pitch. He's not ready to fill that role right now. He needs help. Like the young boy [Daniel] James will need help.

"It's too much for him. it's too much for any 21-year-old you can name. You can't have a 21-year-old as the main man at a club of this size. Strikers are the hardest things to find. That's why they cost the most money. If you can land someone that gets you 25 or 30 goals a season, and he's not exactly what you want, you take him anyway and build the rest around him. You're struggling for goals, that's the first thing you need.

"Where Man United are now, they will take anything!"

Neville insists Rashford could become a prolific striker for the Red Devils but thinks the priority should be bringing in a player who is the right fit for the way Ole Gunnar Solskjaer wants to play.

The former United defender said: "He's still young. I look at [Roberto] Firmino when he first came to England, I look [Mohamed] Salah when he was first at Chelsea, I look at [Sadio] Mane. Sometimes players have to develop into what they are going to become.

"I think United want a striker like Firmino, like [Heung-Min] Son at Tottenham. I think [Solskjaer] wants that type of player.

"I don't think he wants a typical striker who is basically going to be a Lukaku or a [Diego] Costa. I don't think he's looking for that type. I think he's looking for a more mobile type in a front three or a front two. I think this club has always had strikers who can play in pairs, who contribute off the ball.

"I'll make a point about Ruud van Nistelrooy. We won less championships with him at centre-forward than when we brought Louis Saha in to partner Wayne Rooney.

"He was nowhere near as good a finisher as Ruud or as good a striker as Ruud, but the team became better. And that's my point, I don't think Ole wants a striker like that; I think he wants a mobile striker."

Neville compared Solskjaer's decision to allow Lukaku to depart with how Jurgen Klopp dealt with Christian Benteke at Liverpool. "He just chucked him out the club because he didn't suit his style of play. Ole's done the same with Lukaku, and Lukaku is a far better player than Benteke.

"Ole is not going to sign a striker just because he scores goals, because Lukaku would have done that."

Jose Mourinho said: "I don't think he's a 9 that can play against a low block or that can be a target man. I think he's a man of movement, who can attack space and then attack defenders with the ball at his feet.

"I don't think he's a pure 9, so it depends on the model of play. If Ole wants to play the way he played today I think Rashford is the perfect striker for him.

"So, for me, the point is not his age, it's his qualities. For me, he is potentially a very good player in some models of play, in some positions. But as a target man, as a No 9, I don't think he has the 30 goals that a top striker has.

"For me, he can get better and better and better playing the way he did today, playing from the left side, playing with a target man.

"But for him to be the target man in matches where Manchester United are dominant, playing against defensive teams, against low blocks, I think it's difficult for him."
