I’m gonna (Eden) hazard a guess here and say that Newcastle probably already have personal terms sorted with the player, and have just been working with RBL on what kind of bid would be accepted.
Being honest, I think Sesko will be a massive flop in the PL and I don’t think that Newcastle is the right setup for him to develop in, but I couldn’t give a shiny shite about any of that so long as it means we get Isak.
