Former Manchester United cental defender Rio Ferdinand has stated that he believes United manager Ole Gunnar Solskjaer should be making three or four further additions to his squad this summer.

United have been linked with Real Madrid left-back Sergio Reguilon.

Should United end up signing him, Ferdinand believes that Solskjaer should be seeking to sign two forwards and a centre-back, which would turn his squad into a stronger one this season.

Solskjaer has signed Donny van de Beek so far this summer, which will go a long way to strengthen the midfield, especially with Paul Pogba, Bruno Fernandes, Scott McTominay, Fred and Nemanja Matic in the squad already.

It may be the strongest midfield that United have had post-Sir Alex Ferguson.

Ferdinand feels that the club needs to put more money into the squad this summer, upping the quality, which was lacking last season.

Ferdinand, speaking to BBC Radio 5 Live, said:

“I would say definitely after Van de Beek they need probably three or four if they’re going to really compete Players that can go in and actually affect the first team, the first XI.

“And Reguilon we’re talking about, the lad at Sevilla who’s from Real Madrid, he was voted the best left-back in La Liga so really good credentials.

“Luke Shaw I think is unfortunate in terms of his injuries. He’s played games but then he hasn’t been able to sustain a full season without any injuries, which is disappointing.

“But listen, if I was looking at it and looking at the team, in the forward areas I think one or two additions.

“One definitely, maybe two, are needed that can come in and affect that first team and push people, if not start.

“And then I think a centre-back. That area, for me, is where there’s a lack of real, genuine pace and I think the best teams around at the moment have a player in one of the two players that play [at centre-back] in a four that has genuine pace normally.”

He continued “I think Liverpool are the team that’s dominated this season. The two centre-backs can be sat on the halfway line, they’re sitting there purring, waiting to be taken on in a foot race back to the goal and they back themselves.

“And with that, what that does as well, it’s not just about pace – knowing how to defend as well – but what that allows is more players to be able to go forward and pin the other team back in the opposing team’s third, which is, the way the game is played today, very critical.”
