Gary Neville warns Man Utd they face another poor season if Red Devils don't solve problem position

Neville says United must sign a new goalkeeper if they're to avoid another disappointing season. Former Inter and Ajax star Onana has endured two error-strewn campaigns since moving to Old Trafford and had made eight mistakes leading to goals in all competitions by April earlier this year, more than any other Premier League shot-stopper. 

There have been links with Aston Villa's Emiliano Martinez and Paris Saint-Germain's Gianluigi Donnarumma and Neville believes his old team need to bring one of them in. Altay Bayindir and Tom Heaton are the current options for manager Ruben Amorim if he were to drop Onana from his starting XI.

Neville said on the Stick to Football podcast: "You've got to get a goalkeeper. If you've got a goalkeeper and a midfield player, I think fifth or sixth will be achievable. I think without a goalkeeper, it's eighth or ninth.

"That is the number one most difficult position in English football, Manchester United goalkeeper. I think it's the most scrutiny that anybody comes under."

"Donnarumma or Martinez. When they said about Martinez from Villa earlier in the season, I wanted him. His personality. He's got guts. He's got that presence."

Martinez remains a Villa player despite appearing to wave goodbye to the club's supporters at the end of last season. Donnarumma, meanwhile, is being pushed out of PSG after Lucas Chevalier was snapped up from Lille and the Italy international's agent has admitted his client is interested in a move to the Premier League.

Onana has not featured in any of United's pre-season matches due to injury but it is thought he will be available for their Premier League opener against Arsenal on Sunday.
