Paul Merson has revealed the tactical issues he believes Ruben Amorim will need to resolve if he is to challenge Manchester United for the Premier League titles once again.

Amorim agreed to become the new one Man Utd boss from November 11, the start of the international break. The Portuguese, who currently manages Sporting CP, will replace the sacked Dutchman Erik ten Hag.

love had previously held talks with United’s rivals Liverpool, but they were put off by his insistence on playing three at the back.

As such, United’s squad must prepare to play either 3-4-3 or 3-4-2-1 under their new manager.

Former Arsenal star Merson believes it will be a long way for United to succeed under Amorim. The pundit also named the four areas where United may need to sign new players to help Amorim’s system.

“I look at Manchester United and I really think Ruben Amorim has his work cut out for him at Old Trafford,” Merson wrote in Sportskeeda column.

“You could say it probably has an advantage because we don’t expect much. But I look at all the other big teams and they all have a plan in place, Manchester United don’t.

“When you look at the system that Amorim is implementing at Sporting and you look at United, you don’t really know how many players at Old Trafford can do that.

“It doesn’t tick any boxes. Who will be the back three, given that all their centre-backs available for selection are not the fastest? What about the backs of the wings?

“They don’t have a proper goalscorer no. 9, like Viktor Gyokeres or two creative players with number 10.”

Merson went on to discuss United’s Premier League home game against Leicester City, where the Red Devils will be managed by caretaker boss Ruud van Nistelrooy for the last time.

“Leicester did well to salvage a point against Ipswich last weekend,” he added.

“A loss in that game would have been catastrophic for them. Jamie Vardy will need to stay fit throughout the season if he is to avoid relegation.

“I think there’s only one winner in this game, and it’s not Leicester.”
