Davies is a LB and a back up one from almost 10 years ago. He 'became' a CB in a three under Conte, now he's being asked to play in a 2. It's not proper cover. And if he's doing that who's the LB cover?
2 on loan because they're not ready and won't be anytime soon.
Who are the 5? Biss, Sarr, Mad, Benta and? Gray and Berg are teenagers and not ready to provide week in week out cover. Kulu isn't a proper 8, it's an experiment that the jury is still out on.
Spence is a back up RB who never plays and hasn't been trusted by multiple managers at Spurs and on loan at other clubs. It's a hole effectively because he isn't good enough.
This squad is weak. Walker and Trips, Rose and Davies right off the top of my head. Dier, Toby, Jan, Sanchez.
We replaced Wanyama and Dembele with Winks and Sissoko as another example, we went backwards.
I think we're potentially building a good squad for the future but the current one is weak, padded out with youngsters (see above) or young men (Drag, VDV, Sarr, Johnson, Udogie) still learning their trade and suffering (and learning hopefully) in the process, but it's also costing us now.
