On the other hand this could also encourage some players including Dusan and Osimhen who are at Napoli.
But that only refers to a few for the case of Chelsea there might be a difference because with Mbappe leaving or not they will try to get Dusan if that is the best option from Pochettino but if Mbappe leaves and Dusan is one of the options for a replacement then maybe Chelsea should be prepared for the competition that will occur between them and PSG.
I wonder if Vlahovic is the breakthrough striker that Chelsea is looking for. They tried their luck with a number of strikers and although Vlahovic is a good one, is he really that strong? Vlahovic scored 10 goals in the last season, which also includes 2 penalties. To me this is still one of those average performances that would make doubt that he gets along any better in the Premier League with Chelsea. If this doesn't work out it could end the same way as it did with Felix or Havertz when they tried to let him play the striker position.
Dusan is actually a pretty good striker, it's just that sometimes the performance depends on how the coach exploits him.
He can shine at Fiorentina even though for Juventus he still hasn't shown anything that can be said to be great until now.
Joao Felix came during the previous era and Pochettino did not really expect it because it did not fit the scheme he was going to do as for Havertz actually for me personally this is a little regrettable especially since several Chelsea players who left joined other big clubs which of course this makes Arsenal who brought Havertz, Manchester United who brought Mount and Manchester City who brought Kovavic clearly benefited.
At the moment we only need to see how this will end whether Dusan will indeed go to the EPL or not at this time it is still uncertain.
