Ten hag haven’t gotten what he needs from Onana and am sure he will be disappointed right now. He wants a goalkeeper that's good at leg work, which he thinks Onana is just the right goalkeeper for that. But how do you want a goalkeeper to play that pattern of football when the defense of the club is very weak? Before Onana will be able to play that pattern of football that Ten hag needs, then Ten hag will have to work on his defense. The Manchester United defence is so poor, and that’s one of the reasons why Onana is always conceding many goals in most matches. Defenders are supposed to be protecting the goalkeeper, but no defender is protecting Onana.
Onana is sometimes not at his best during important matches such as in the Champions League where he often makes blunders which result in Manchester United losing. I think he hasn't found his best form yet at Manchester United because when Onana was still at Inter Milan he was able to perform well because Inter Milan had strong defenders who were ready to help Onana when the opposing team attacked them.
This season, Manchester United has a defender crisis because several defenders are injured which makes their defense not very strong, so Onana has to work extra hard to be the last wall in guarding the goal. In the match against liverpool Onana was able to block several accurate kicks and I think he should do that job in every match he plays.
