€140M sounds like a lot but how often did we think that the amounts paid for transfers can't be real anymore? In this market nothing is surprising anymore and it depends on which club wants Osimhen. If it is a club like PSG they would pay whatever it takes. PSG is actually a good example because they have demand at the end of the season. They could need someone like Osimhen I think. But nobody knows what his personal preferences are besides money. Manchester City has Haaland. It could even be Liverpool since Firmino is leaving in Summer.
It's true, the value of such an expensive player is no longer surprising. Even in the past Neymar had a value of €200M, Coutinho €130M and there are many other players who also have the same market value. But Osimhen probably won't be much more, and suitors should be good enough considering the value and quality.
Firmino will leave on a free status from Liverpool, this will be a bone of contention for several Premier League teams. Firmino's quality is recognized, and I think he is still very good to play in competitive leagues such as the Premier League, La Liga, Serie A and others. Barcelona also need a striker, but Firmino's future has yet to be decided where he will go.
Yes, Neymar was even 222 million if I recall that correctly. It was absurd to be honest when I first heard about, but today it is already normality. The money Ronaldo is earning, or the signing money for Mbappe's contract extension, which is not 100% public, but numbers can be found ranging from 100 million to even 206 million Swiss Francs as I just read.
At first when I read that Firmino is probably leaving Liverpool, I thought that he would be a good offender for Bayern Munich just for a season or two and then perhaps as a back up when they find a new one. But since Bayern then extended the contract with Choupo-Moting, it was obvious that it is not going to happen. Though I think he would have fit well into the Bayern team with his technique and his attitude to work hard on the pitch.
