Kvaratskhelia also had a very successful Euro tournament. He had one of the most important roles when Georgia was at its best. He will undoubtedly be one of the most important weapons for Napoli next year. Napoli must have thought that they got the maximum benefit from Osimhen, or they must not have been able to convince Osimhen to stay, so they chose to sell. Osimhen is a very strong player. He would have benefited Napoli greatly if he had stayed.
In fact, now there are lots of offers coming in for Kvaratskhelia, especially after his good performance at the Euros made several teams start to be interested in bringing in Kvaratskhelia.
This is worrying for Npoli because their two strikers are likely to leave, Kvaratskhelia and also Osimhen and I think both players are realistic in choosing a path to make their careers brighter in the future, namely by moving to a top team.
It is said that Kvaratskhelia will determine the future of his career after the Euros, whether to stay or leave.
But don't overreact to this, I think the new Napoli coach knows what he has to do to build the Napoli team even without Kvaratskhelia and Osimhen.
