I'm a Manchester United fan, which is why you see me talking about Manchester United. Manchester United's performance against Fulham was so poor, even though Manchester United was at home. With the 1-2 loss to Fulham, our chance to qualify for next season's UEFA Champions League is slim. Fulham deserved the win they had against Manchester United because they performed better than Manchester United.
Onana again did not reflexively catch the ball so he just let the ball into the net. 
Onana's same mistake is still being made.
Manchester United for the chance to qualify for the Champions League? It's still far away even though there are still many matches but I'm not sure there is a significant enough change later, they can only win the Europa League.
I thought the Fulham game would end in a draw but it didn't. I was honestly quite annoyed why did Onana let the ball go was it because he was out of step? But as I said Onana often makes this mistake.
I don't think Onana is to blame for that match; he can't follow that ball because Iwobi deceived him, and Manchester United has issues when they are drawing the game 1-1 they didn't claim down on the pitch they are rushing to score another goal, and Fulham gets the opportunity to add another goal if Manchester claims down on the match, I believe the match will end in a draw. You are correct, it will be very tough for Manchester United to qualify for the Champions League next season they can only qualify for the Europa League, and even if they qualify for the Europa League they will still be playing awful games, but they can't win the trophy let us see whether they can win the remainder match in the league so that they can qualify to the Champions League next season, is Bruno that is performing very well in the club, if Bruno is not in a game Manchester United will suffer very well in a match.
