The Cameroon stopper has had a torrid spell at Old Trafford since joining from Inter Milan for a big fee.
Onana hit several shots, the last of which put the Red Devils 3-1 up against Galatasaray.
The result dashed United’s hopes ahead of their final Champions League group game against Bayern Munich. Carragher spoke about Onana’s problems, recalling how he felt after his shocking mistake against West Ham in 2008.
In his Telegraph column, the former Liverpool star said: “A lot of us have been there after a bad game knowing that your contribution is crucial to the outcome of the game. The match ended in a goalless draw.
We won a corner in the last minute, West Ham went on the counter-attack, Freddie Ljungberg was sent off and we gave him a penalty.
“I was scared to go home because Mark Noble had scored, West Ham had won 1-0 and I thought the defeat was all my fault.
After 10 years in Liverpool’s first team, it was comforting to get a loan from a bank. “Nobody at Anfield said my career had to end, but I felt really bad and I couldn’t say anything to make me feel better.
Onana must have felt lonely working full time on the flight back to Manchester on Wednesday night. “It’s not a great place to live, but Ten Haag has to worry about its future.”
Following the draw at Galatasaray, Onana considered drastic measures to revive his stuttering career. It has been suggested he could turn down a call-up to Cameroon’s Africa Cup of Nations squad in a bid to maintain his status as the club’s number one.
The Red Devils have Turkish goalkeeper Altay Bindir on the bench and despite playing less than a minute in the starting lineup, he was expected to start in Onana’s absence.
The latter has made 20 appearances for United so far this season, keeping seven clean sheets while also conceding 33 goals.
He hopes to keep Erik ten Hag’s faith alive next weekend. United return to Premier League action on Saturday evening when they travel to St James’ Park to face Newcastle.
