Arsenal are said to be interested in Kvaratskhelia and Kudus both. But I don't know if they are still willing to spend much more money now. Especially Kvaratskhelia's cost would be very high for them. Both of them are really skilled players so transferring even one of them would be quite beneficial for Arsenal.
I think Napoli's demand for Kvaratskhelia will be very high. There is no release clause for him and I think they would want 100 million euros minimum for him. Therefore going for Kudus might be better if they don't want to splurge on a player again like they did with Rice.
With Manchester United going for Sofyan Amrabat and already solidifying Mason Mount & Andre Onana I don't see how they can possibly get somebody worth Mbappe so will likely go with Rasmus Hojlund instead.
I can see Arsenal signing both Kvaratskhelia and Kudus so to add to the squad's talent after confirming Declan Rice earlier during the transfer summer window.
Liverpool is said to have the most likely scenario of signing Kylian Mbappe if he does decide he wants to make the EPL home for his future club.
