Well FC Chelsea was buying players like crazy during the winter transfer period of the last season. After that crazy shopping trip they had way to much players in their squad and it was obvious that they had to sell a few of their players in order to get the head count of their players back to a reasonable amount. I think it really is sad for the fans of FC Chelsea that they are not selling players that did not play that big of a role anyway but instead they are selling very crucial players like Havertz and Mason Mount. So looking at the huge transfer activity of FC Chelsea in the last 8 months or so i have to say that i don't really see the squad stronger now than before.
Well that's your assumption, if we speak from the data, currently has the best result in friendly match where they won 5-0 against Wrexham today. Havertz and Mason Mount might aren't good players, although they are still young and they have a chance to increase their quality.
It's either Pochettino is smart to find a problem in Chelsea or he's stupid for did this fast regeneration by selling their important players when they won champions league trophy.
