Seeing Kane's condition to move to the EPL team is actually still very difficult. Apart from the fact that he is still comfortable at Tottenham, it is clear that Tottenham will not let that happen, especially since two big clubs, Manchester City and Bayern, have had their hearts broken because of this player.
Osimhen still could but it's clearly going to be a big price if they do try to bring in this player. It's not impossible that the clause will be bigger later, especially since he is the top scorer and a strong candidate to bring the Serie A trophy this season.
I think the same way, I mean I know both players are performing very well and these two got different playing styles but still Kane is an old player in Tottenham and he playing there for a long time also compared to Osimhen he is older and can't be a good investment for the future of the team while in the other hand, Osimhen can be an easier target and can grant a better future for the team.
The problem now is that if their target is clear to Osimhen it won't be easy either. Apart from Napoli, which will continue to try to keep its players from going anywhere, of course, it is certain that there will be lots of big clubs who have the same interest later.
In the end they have to be prepared with all possibilities including setting up funds which are certainly not small so that other clubs cannot be surpassed in the hunt for these young players.
