Louis Saha has urged Manchester United to provide competition for Andre Onana, who he says has been turning in "unacceptable" performances.
Onana has come under fire this season for committing a number of mistakes that have led to goals for United's opposition, with the goalkeeper often blamed for his part in the club's poor record in the Premier League this season.
Former Red Devils star Saha, who won four major trophies during his stint at Old Trafford, has joined in on the criticism levelled towards Onana.

Speaking to Paddy Power, Saha took aim at the lack of competition within the United squad pushing Onana to be better.
“There is a need for every player at Manchester United – apart from Bruno Fernandes and Amad Diallo – to feel threatened with competition," Saha said.
"No one has shown that they deserve anything in the next game. The manager can challenge and criticise them because it’s not good enough.
“The backbone of this team, from the back four to the centre forwards, it’s so important that they don't make mistakes.
"Unless you can guarantee that you’re not going to make mistakes, you should not be considered as a guaranteed starter in any position. None of those players should be guaranteed anything.
“If you don't have a confident goalkeeper he has to be challenged. Those performances are unacceptable, it’s not normal!”
