What's actually Onana doing?

He should able to save that because it's an easy shot. Not surprising to see his rate is 3.2, he played really poor in this match.

You should be applauding the shot technique by Gibbs and not criticising Andrea Onana. We should also be talking about the build up to this goal and how Bruno Fernandez messed-up with that pass. Below is the image of Manchester United manager Ruben Amorin defending the best goalkeeper in the Premier League competition currently. I hate the fact that he is not getting the flowers he deserves.
