There is not any news about Kane and Bayern Munich we know he is an important player for Tottenham, that's why I think they will not lose their players easily, and even if Bayern Munich spends too much money on this player, still there is a chance for say Kane will stay in his team that's why maybe Bayern Munich should have negotiations with other players too.
It is because of these two reasons that Bayern Munich must have negotiations with other players so that next season Bayern Munich can remain strong and even try to be stronger than before. Because Bayern Munich needs to make a big breakthrough next season with coach Tuchel in the UCL and also in the Bundesliga, so Bayern Munich themselves don't need to spend more time waiting for players they are still unsure about getting.
Lukaku is a player who is under contract with Chelsea and since Chelsea lost many players this season to Saudi teams and they are seeking other players I think Chelsea will even accept to let Lukaku leave their team if they get enough money from this deal but Lukaku is not a very important player for Inter Milan to spending more for this player.
If no team wants to have Lukaku for next season, he must also stay at Chelsea although Chelsea themselves are also happy if a team wants him for a fairly suitable price this summer. Apart from that, Chelsea itself will not lose too much if Lukaku does not get a transfer to another team at this time because Chelsea can still use him for next season even though at Chelsea there are already more young players whose ages are very different from Lukaku.
