You're wrong, no?
Let's not pretend BW is anywhere near this guy in terms of talent and physique, but you are right to say he won't instantly replace him.He’ll be a rotation option for the first couple of months. We’re already changing 2 pieces of our team with Partey and Xhaka leaving. People who think he’ll instantly replace White are in for a surprise IMO.
Zynchenko, Saliba, and Timber, I don't think I've ever seen that much technical quality in defense. No way teams will be able to press us.
It's also important to mention that if we get Havertz and with so much technical quality in our back 4, they will actually have great targets in front of them. Havertz and Jesus will constantly be on the move and we can target them in transition, Timber and Saliba will enjoy that. Absolutely perfect planning from Arteta and Edu, has to be said (if these transfers ever happen)
