Get ready for Premier League transfer records to happen in this transfer window. £120M or more would be a fantastic transfer fee and most recently, Liverpool seem to be doing a deal with Newcastle United to discuss Isak wanting to move and Liverpool the goal according to some sources on the internet.
If that happens, Liverpool is doing something out of the ordinary.
£265M has been spent by Liverpool in spending 4 players.
If Isak's price is £120M, then the total is £385M.
120 million euros is a truly huge sum of money. I don't think it makes sense for this player to be valued that much. He may be the team's star player, but if a player is worth over 100 million, I think he should be capable of much greater things. I don't think he'll be a good player statistically.
The latest transfer rumors have mentioned 140 million euros for Isak. Even players like Ronaldo and Griezmann have transferred for less than that

First 95 million for Ekitike and then another 120 for Isak? I follow the Bundesliga more closely and I would never have believed that Ekitike would have been worth 95 million €. Even sums over 30-40 million would have been too high, I would have estimated his value at 20 to 30 million.
Something similar applies to Isak. The only difference with him is that he has experience in the PL and has already proven himself there. But for me he's never worth 120 million, more like 50.
After the transfer of a very expensive striker, it makes little sense for me to get an even more expensive striker.
