I agree with you. Chelsea have serious problems in their defense. I am confused why Chelsea increase the number of goalkeepers even though currently there seems to be around 8 goalkeepers in the Chelsea squad. But it seems true what X-ray said, Chelsea increase the number of goalkeepers not only to find the best and strengthen their defense, but to do some business and get profit from the player's price.
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. Because a team must be better from all lines and more importantly is the defense side apart from the front side which must also have fast finishers so that there are goals from each match. But I don't understand what Chelsea is doing now so that they can have that many goalkeepers.
Between for business or used to see a goalkeeper who has the right skills for Chelsea. So from my thinking, it is likely that some of the goalkeepers that Chelsea currently have will be loaned to several other teams while the transfer market has not closed, it is possible that Chelsea will take this opportunity to get profit to cover the money that has been spent a lot to recruit new players this summer. Chelsea should indeed focus on several lines that must be added with new players, but we also have to see if Chelsea has a little difficulty in bringing in reliable attacking players like Osimhen who until now has not given any confirmation from Napoli. And if that can happen, of course there will be many who say that Chelsea will rise.
