Former Chelsea midfielder Craig Burley thinks that Man Utd need to sign four more players this summer following the capture of Nemanja Matic.

The Red Devils have already signed Victor Lindelof from Benfica, and according to latest reports, they are closing on a move for Matic.

"I still think they will need another three or four (after Matic)," Burley said on ESPN FC.

"Lindelof's been playing at Benfica but he's still a relatively young man and this is another step up for him.

"Yes, he's a Swedish international but I still think they need more.

"They need that striker and maybe a back-up to that striker and I still think they need to get a bit more pace out wide.

"(Anthony) Martial hasn't cut the mustard, we've seen (Marcus) Rashford play out there, it's not his position.

"He's got to make sure, (Jose) Mourinho, is putting square pegs in square holes, and not the opposite."
