I agree with you, but at the same time we need to realise that Conte is a great coach. He elevates players to another level. So the level we see our players at the moment aren't their peak. I believe the players have another level they can go up.The only issue for me is I don't think our defence is elite. We haven't strengthened to a necessary level at CB (yet).
I know our defence did well under Conte last season, but on an individual quality basis it's still lacking and over the course of a season I do feel Davies and to a lesser extent Dier will make mistakes that the likes of City and Liverpool's back line won't.
Lenglet is a welcome addition, we will have to see if he is first choice over Davies.
For me, going into this summer, LCB, CM, AM, RWB and LWB were the positions we badly needed to upgrade. And we also needed another attacker for depth, and personally I wanted an upgrade on Dier but I understand others might disagree on that one.
LWB - Perisic
CM - Bissouma
Attacker - Richarlison
Undoubted quality in those positions now adding depth.
RWB will likely be Spence, but not sure that's an upgrade.
LCB - Lenglet, unsure yet how much of an upgrade that is on Davies.
We still need an AM and I still think we need a top CB to come in. I think otherwise our defence will be found a bit lacking this season in those tight games. CB is so important.
If we sign a top CB, Lenglet can cover both LCB and CCB.
Conte is the perfect Moneyball coach. Brings out the individual elite level in the players he coaches.
But i do agree we still need another CB and a CM and I think we are good for the next season.
It's time to believe and trust the process.
