Liverpool couldn't afford what we would ask for Jack without selling one of Salah or Mane, and then why sell them to replace them with Jack around the same cost.
City buying him would be like those big money FM moves where in Jan the player requests a transfer because he doesn't get enough playing time. trying to take away my villa lens, I just don't think he would be worth spending over 100 mil on just to be rotated by Pep and his system.
United is the one that's a mystery for me. They wanted him last summer but didn't pay what we wanted. Chased Sancho as well and didn't want to pay the 120 mil that Dortmund wanted, and its just been another covid hit financial year so I don't know if they have the money to buy him while also buying players that they need -- as @nick76says above, they already have starting level players in the positions that Jack plays for us.
The wild card for me is PSG and Poch. I would think they could afford him, and if they sell Mbappe they would be in need of another high profile attacker. Would he want to go there though is the question.
