On paper, I don't actually think our squad is bad.
Lloris is still a brilliant goalkeeper and saves us a lot more points than he loses. The fans do tend to go through phases of "Lloris is shit" to "What a goalkeeper" though so don't let that skew your judgement
Defence is obviously our weakest area.
But midfield we have Ndombele, Lo Celso, Dele, Bergwijn, Son which is a great selection of talent, you then have Lucas and Lamela, who aren't truly good enough to start week in and week out but both have proven to be able to change games at times when they do come off the bench. That's without even mentioning Winks and Sissoko who again, provide decent depth and can be useful in certain games.
Kane as our only attacker is a problem of course, but you'd argue we had a top 6 squad when we finished 3rd in 15/16 and Kane was our only attacker then too.
It obviously has areas it needs improving:
RB, CB, LB and DM most importantly as we have failed to really replace what Walker, Rose and Wanyama meant to us - I do think the loss of the aggressive full backs and a defensive midfielder has hindered our centre backs but we still haven't really replaced Vertonghen and that left sided area, whereas I think Dier/Sanchez/Tanganga could quite easily fill in at right sided centre back WITH the right partner on the left.
It's definitely top 6 material.
But it needs significant improvement as well as great coaching and a system that compliments every single player if we are to be that challenging team again that was hard to beat and feared before a ball was even kicked.
Lloris
RB - Dier* - CB - LB
Lo Celso - DM - Ndombele
Bergwijn - Kane - Son
* Dier/Sanchez/Tanganga
Of those listed, that is a highly talented squad with players who only want to move forward with the ball and aim to play great football. Getting the right players in however has never been an easy thing to do for Tottenham and how soon can we really get 4 new players, especially in the defensive third, working together and forming a cohesive unit?
Not really sure where someone like Dele fits in to that system however, though if it came to it, I wouldn't be against selling Dele if the price is right and bringing in a monstrous DM like Partey from Atletico Madrid for what would likely be a similar fee. (I believe he has a release clause)
