He flops. Given how young he is and how cheap we will get him for, we won't lose much and I suspect another EPL team would give him a shot for around 20m.
He flops, and he will still be starting for another couple of years because Barca is super loyal to GK, and then he will be loaned out until the end of contract, probably with us paying part of his salary.
25M for a GK is like 50M for a CB, he will be the 15th most expensive GK ever, with some of those ahead of him either in ancient history, or over reported deals like Neto. It isn't cheap for a GK, it just doesn't affect the rest of the plans.
Look, I love optimism around transfers, but there is no such thing as risk free transfers with signings like this.
There is a lot to like with Joan, he is fairly young, he knows the City and the league along many of our player that were in the Youth and Olympic teams. As as shot stopper, he conceded only 88% of the goals he was supposed to concede. In Comparison. MATS conceded over 100% in past 2 seasons, his best was 75% in 22/23 year. Tek conceded 100% this season.
He is dominant in crossing, he has potential in sweeping as his numbers weren't bad. He has the tools to be elite.
So, it is great to look forward to those attributes, but OTOH let's not get ahead of ourselves and think he is some sort of sure things with no drawbacks.
