So what do you think hag will do? Play Dean or go for a new goalie, also who's on the market?
Maybe onana is an option?
There is no logical reason to continue with De Gea and I just don't see him doing so. He doesn't fit anything at all about how he gets his teams playing.
Henderson is a comfortably better fit for the way we try to defend higher up the pitch, it was there for all to see last season when he was given a run in the team despite people seemingly rewriting the whole time in their head because he made a mistake against Liverpool. Both the individual and team statistics prove this and frankly it is baffling that somebody at the football club hasn't seen that and that we have persisted with De Gea when he caused us so many issues with his inability to sweep behind a high line (worst in the division), deal with any kind of balls into the box (worst in the division) and his below average distribution (lower third of the division), and that's without the other critical aspect of goalkeeping which is not measurable by any statistic - communication, we know Henderson is loud and a talker on the pitch whereas De Gea is incredibly quiet for a goalkeeper.
To compare the two (PL only);
De Gea this season has dealt with 3.1% of crosses into the box, Henderson dealt with 8.6% last season.
De Gea this season has swept outside the area 0.24 times per game, Henderson swept 1.12 times per game last season.
De Gea this season has thrown the ball out 112 times in 34 games, Henderson threw the ball out 61 times last season in just 12.5 games which would suggest Henderson see's an opportunity for a breakaway much more often.
There isn't a lot in the passing stats.
And before the "oh but De Gea is so much better at stopping shots" etc, De Gea's post shot xG this season is currently +7.5 (second best in the league, fair play), in Henderson's only full season of PL football at Sheffield United, his was +5.2 which would be good for third best in the league this season behind Jose Sa & De Gea. For reference Alisson who I consider to be the best overall goalkeeper in the world, is at +4.4 - which is why I don't like this stat particularly as it doesn't take into account the opportunities the goalkeeper had previously had to stop an attack becoming a shot on goal - De Gea is always likely to be
So basically the one thing De Gea is good at, he isn't even that far ahead of Henderson at in reality. And I wouldn't even say I'm a particularly big fan of Henderson, he's just earned his opportunity and I agree with others than the budget is better spent in other areas this summer, I just disagree which goalkeeper should be the clear first choice into next season.
In terms of delving into the transfer market, it depends what they want to do. If they don't rate Henderson but want to go with a relatively inexpensive goalkeeper with Premier League experience then you've got Jose Sa, Robert Sanchez & possibly David Raya who are the stand out options. If you want to go all out and spend big money then the best option is probably Mike Maignan. The reality is that replacing De Gea really isn't a difficult task, as bringing a goalkeeper who is relatively average across all areas would still be a considerable improvement overall.
