"I know the spotlight is on Onana a lot in this United team, but the mistakes we've seen are as a result of a combination of things," Babel said, via Metro.
"Onana, at Ajax, had a back four in front of him who were all incredible with the ball at their feet. Respectfully, if Onana is then playing with Harry Maguire, then that immediately puts Onana in trouble, because he’s playing with defenders who aren't opening themselves up, or making the right runs, so that Onana has options to play, and that puts him in trouble.
"At Ajax, Onana had the privilege of four great defenders, and Frenkie de Jong in front of them. Onana is a great goalkeeper, but they made him look even better. If a set of players don't work well together, it makes some of those players in particular look terrible. In this case, that’s what Onana has experienced.
"Absolutely, though, some mistakes have been completely his fault; sometimes you question his positioning, or you just wonder what he’s doing. He’s not been himself in my opinion, but from what I know of him, and what I’ve seen, he’s an incredibly talented goalkeeper, and I hope that more people can see that next season for Manchester United."
