Manchester United legend Gary Neville believes the club must sign a top class goalkeeper.
Neville feels the Red Devils have been let down by David De Gea mistakes in recent seasons.
And the former United right-back says the club must sign a goalkeeper in the same ilk of his former teammates, Edwin van der Sar and Peter Schmeichel.
"Your goalkeeper, to win a league, has got to be exceptional," Neville said, per Eurosport.
"I said three or four years ago, Jurgen Klopp took me on publicly, but you're not going to win a league with [Loris] Karius and [Simon] Mignolet.
"That's not to say they're not good goalkeepers, or decent goalkeepers, but which team do you know that wins a league…there might be the odd one, but they usually have great goalkeepers, or goalkeepers that have had a great season.
"Ederson is a great goalkeeper, Petr Cech, [Peter] Schmeichel, [Edwin] Van der Sar, even Kasper Schmeichel for Leicester, David Seaman, Alisson, you've got to have a great goalkeeper.
"We have to start asking questions about David De Gea. The mistakes are coming more regularly now and they cost points.
"The game-winning saves are coming less, the one-on-one saves are coming less. I think that has to be a question that Ole [Gunnar Solskjaer] has to answer.
"Then there's the question of Henderson, are we saying that Henderson is going to be the number one for Manchester United?
"That might be tough on Henderson, but to chance it - do you gamble with winning the league? That's the first question, is the 'keeper right? That's number one, deal with the 'keeper situation.
"Your goalkeeper, to win a league, has got to be exceptional."
