Spurs have all but signed Reguilon and Bale on loan, whereas every report says unless Sancho throws a strop, he isn't going anywhere (and thats assuming we pay what we refused to pay before August 10th when Dortmund was actually willing to listen). We aren't signing Sancho.
But if you look at the front 3, Spurs can choose between Kane, Son, Lucas, Bergwijn and soon to be Bale. I dont rate Bale much, but as depth he is better than James and Ighalo. They also have Bergwijn as a squad player who would likely walk into our starting 11 on the right (or at the very least, rotate with our front 3). They also have the Europa League where its easier to rotate than for us being in the Champions League.
Then look at their fullbacks. Doherty, Reguilon, Aurier and Davies. Much more quality on the ball, more attacking quality equaling more suited to bigger clubs. Good backups for both sides, while we have good defensive fullbacks starting, a 20 year old Williams as first backup to both sides and then random trash behind that. We have no fullback depth.
Like I've said, all we have is midfield depth, and then a bunch of injury prone players as CB depth. Left back, right back, right wing, left wing, striker... all positions that you generally need to rotate more to maintain freshness, especially the way we play, is literally unusable depth. Its just a shockingly bad position to be in. You take out Son and Kane for Spurs, they can still start a front 3 of Bergwijn, Lucas and soon to be Bale. Take out Martial and Rashford and our front 3 becomes Ighalo, James and Greenwood. Take out Aubameyang and Lacazette from Arsenal and they still have Willian, Pepe and Nketiah, Martinelli or Saka.
Its so painfully obvious that we're going to have an injury crisis. Only it won't be an injury crisis in terms of numbers, it'll be a crisis due to a lack of planning. Last season we similarly had a "crisis" when Martial and Pogba got injured. 2 players shouldn't throw you in a crisis. Its just a lack of planning. Injuries will happen, but they'll happen more frequently and more severely if you don't have depth to rotate your players, and then going further they'll have a bigger impact as those exact players you avoided playing to rest a starter here and there now has to play multiple games from the start.
