I think Rom is in a tricky position if he goes abroad hes not going to get anything like the wages or profile he does in the PL. While teams like Juventus or Bayern can afford say 80mill, its a significant outlay for them and as such they wont be rushing into any deal.
If he leaves us and moves to another PL team where is he going to go better that doesnt have the position he plays filled:
Utd: Ibra, Rashford, Martial
Chelsea: Costa, Bata
City, Aguero, Jesus, Ineach
Spurs: Kane, Jansen, Son
Arsenal: Sanchez, Giroud, Perez
Hes not going across the park thats for sure.
He will have the same problem, he had when he came here, he may not get the game time to play at clubs with CL football next year. He would go nuts without regular football.
