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.
Arsenal looking to add more players? The Gunners are serious about business this summer, with no time for dithering and an objective of signing additional players all through the transfer season. Mikel Arteta appears dissatisfied with the current roster; he is ensuring that he will face challenges in challenging premier clubs this season; also, the club has ultimate targets to meet this season. Arsenal's pursuit of Khavicha Kvarastikhelia from Napoli is not going to be simple; they may focus on the specific contract that is possible, such as Kudus, who would be pleased to come to the EPL.
