Rio Ferdinand has named the four players he believes Ole Gunnar Solskjaer should sign to galvanise the Manchester United squad.

With Solskjaer struggling for numbers in midfield after injuries to Paul Pogba and Scott McTominay, Ferdinand believes Napoli's Fabian Ruiz would be the best addition to reinforce United's options.

In defence, Ferdinand suggested Ruiz's team-mate and a long-term target for United, Kalidou Koulibaly, would be the strongest possible signing while he also suggested Boca Juniors midfielder Agustin Almendra as a 'wildcard'.

Ferdinand then later underlined his admiration for Paris Saint-Germain striker Edinson Cavani, who is reportedly available for a transfer in the January window.

'Just thinking.... I would 100% go & get Edinson Cavani. Huge experience, Goalscorer, Work Ethic & Great Pro who the younger players in the squad would learn a lot from!'

Midfielder Ruiz, 23, has established himself as one of Napoli's key players since joining the Serie A side from Real Betis in 2018.

He is a Spain international and has been linked with both Real Madrid and Barcelona.

Koulibaly, meanwhile, is another mainstay of the Napoli squad. He has long been linked with United with a mooted fee in £90m region.

Cavani has only made 11 appearances for PSG this season and has found his chances restricted following the arrival of Mauro Icardi last summer.

Almendra is a 19-year-old midfielder at Boca who is a regular in the first team.
