After watching Manchester united defense last night I'm convinced that Onana will not last in my team.
Logically, Goalkeepers that faces the most shots on goal, which often leads to saves are the best to have, Because if you look at the amount of players that gets relegation probable keepers, and the difference between keeps that concedes the most clean don't often end up with most by goalkeepers, why do you think it's like that.
Ederson wasn't in the top 5 goalkeepers with the most points last season, despite Man City conceding the least amount of goals, joint with Nick Pope but had faced more shots and save than Ederson, with how awful Chelsea and below par Liverpool were last season, Allision had more points than De Gea that had at least 3 or was it 4 clean sheets more, while Raya who finished as the number 1 GK with most points last season had 11 clean sheets. Ederson finished as the no. 10th GK with most points at the end of the season despite not conceding many goals, because if City keeps a clean sheet the most you're likely to get from Ederson is just 6 base points, because he doesn't get to make more than one or two shorts on target.
That's was why Kepa was the best choice for the second half of the season for nay player because of the number of saves he get to make, and if that comes with clean, you'd be sure that some bonus points would follow suit.
If Onana were to be 4.0-4.5m I'd be locked in on him already, because I'm sure he'll make a lot of saves, due to the Man United defence, because why else would Thomas Kaminski of Luton despite conceding 4 goals still gets 3 points, but Jose Sa that conceded just one and get 2 points.
