Alexander Isak the player of Newcastle had an amazing performance in all the games we saw from this team so far and because of the good performance he had in Newcastle, it seems there are some teams that want to have this player for the next season.
Tottenham and Arsenal are two teams that sent offers for Alexander Isak. However, Newcastle said they are not going to let Alexander Isak leave unless they pay 130 million euros for this player which is a huge amount of money for any team but I don't think if they can even make the team to spend this money for a player like Alexander Isak.

I'm more confident that Newcastle will keep Alexander Isak in the next few seasons because I'm sure Arsenal or Spurs won't want to spend 130m just for 1 player and Arsenal usually prefer to look for players who are younger and have a price below 100 million.
Isak contract period with Newcastle is still very long and Newcastle condition is currently in an inconsistent state which requires support from players like Alexander Isak.
so it is very likely that they will be retained and the reason why Newcastle said they would let the player go was if another team was able to spend a large amount of money, in fact that is just one way of retaining the player because surely Spurs and Arsenal will also think longer about spending 130m.
this case is the same as the offer made by Napoli last season when Osimhen was offered at a price of 100 million and it was an effort to retain the player.
