I'd love Wirtz. I just don't see us forgoing additions at CF and wing to bring him in for the bulk of our summer budget. If we are competing with City for him, you have to expect that he will get wages over what they just gave Marmoush, which would be well over 300k per week, in addition to a 100m plus transfer fee. That's a significant outlay for us even with our financial position and it might be deemed too expensive given the needs we will still have in the attacking line. I don't disagree that he would solve a lot of issues with our current setup (provided Havertz and Saka return healthy) but still think we need additional reinforcements with our attack.
Now if Berta and Arteta are able to really convince KSE to go for it - a summer of Wirtz, Sesko, Zubimendi and Semenyo would put us in the absolute top tier of the continent.
