That many goalkeepers will definitely be very wasteful for a team because Chelsea will only use a few and it would be more ideal if Chelsea could sell half of that number to other teams and buy some other defenders to fill their defense to make it better.
I don’t know what Chelsea is doing with so many goalkeepers when they can only make use of one in a match. I don’t really think goalkeepers should be what Chelsea will be fighting for right now, there are other positions where Chelsea is performing poorly that they need to fix. Chelsea's defense is just too poor, it was just too easy for their opponents to penetrate during the preseason matches. I think they need to fix that, because no matter how good a goalkeeper is, if the defense is poor, then people will think the goalkeeper’s performance is poor. When Chelsea are singing, they should focus on quality players and not just signing random players.
