I don't doubt you've built good teams, but 2021 is in the past and what I saw today was no team. I couldn't see what you were trying to do and I've always felt that good teams "have a plan" and today the plan seemed to be to get on the coach, play a game and go home.
I do think you need to pick a good manager (not sure Pochettino is the answer) and I thought Potter was a good choice. Once you've got the manager, back his judgement. I know you've done well "hiring and firing" when it suits, but I do think it's been the quality of players in the past who've done that. Let's be honest, me and you could've managed Chelsea with the players they've had in recent years. However, at the moment, it seems the team needs a manager and they don't seem to have one as Lampard is out of his depth.
However, I don't see too many players that - for example - I'd take to City in that squad. I just think the next manager has a massive job on their hands.
