Honestly I'm still wondering why is Chelsea putting in so much effort on their keepers, they are not going to have only keepers play the game on the pitch for them and they may not even get to use all of the keepers so it's really a thing of concern why the much investment in goal keepers this season, it makes them appear like they have got almost not enough plans that is supposed to get them the much they will be expecting from the new season expect they are looking forward to recruiting a host of keepers who will be sold out later.
Until now I am still thinking about the reason why Chelsea continues to look for a goalkeeper and I had thought that Chelsea most likely really wanted to build a strong defense this season. But if that's the case, Chelsea last season was actually not a problem about bad defense but a slightly weak attack line since the beginning of the season even though at the end of the season Pochettino managed to bring Chelsea up to the top 6 but this season should not need to spend too much just on defense.
A little strange but I'm sure everything Chelsea is doing right now must have something planned that we don't know yet but for now the right reason is just to strengthen and prepare a defense that is ready in every competition that will be pursued this season.
