I don't think so, Niclas Füllkrug is not enough for Bayern Munich and this player is worth 13m on transfermarkt while Bayern Munich is trying to hire Harry Kane who is a top-level player and they are ready to pay 100m for this transfer.
Even if Kane doesn't join Bayern Munich, they can still try other options like Osimhen from Napoli.
I think that previously Fullkrug had been linked with rumors of Fiorentina but after seeing the data there are so many teams from the bundesliga who are interested in signing him. Maybe for Bayern Munich the market value is less challenging to bear the burden of a big club, so they are still looking for a striker who is commensurate with Harry Kane.Even if Kane doesn't join Bayern Munich, they can still try other options like Osimhen from Napoli.
Osimhen has been repeatedly linked with Bayern Munich but so far Osimhen has not been touched at Napoli and at least if Bayern Munich starts to get serious they should immediately make an offer for Napoli's key player. Given that currently there have been no official offers from other clubs since this season ended last month.
