Not the person you're responding to but its not about the money. Of course we could spend hundreds of millions right now if want to - we have a sizable war chest built up through prize money and good transfer business.
The problem is that A) the big name targets are currently not available (Musiala, Wirtz, etc.) and B) we don't have much room in the squad to accommodate a signing that would require large playing time.
Say City throw 140 million euros at Bayern right now and they somehow agree to let Musiala leave. He'd be taking minutes off of KDB and Foden, and I don't think either of those 3 players will be happy to sit on the bench in big games. It's the exact same reason Alvarez left a couple weeks ago.
City are wisely waiting until next summer to make a big move and show their hand. There is no rush, we have an incredible squad for this season and I have no doubt we'll make a huge offer for either Wirtz or Musiala next summer (providing they come available).
