If he couldn't get premier League was always going to be a club in the champions League, though he wanted to stay in premier League. That didn't happen as clubs wouldn't pay (high) loan fee and/or commitment to buy at and of season. Personally terms were agreed with one but clubs couldn't agree.
Europe was always the backup, lots of interest, but wanted CL football and gala covering wages. Not a commitment to buy, but he's a talented footballer so here's hoping he shines.
Personally wanted another season out of him, but premier league clubs turned his head and then there was no turning back. Saints allowed him to talk to others, couldn't agree fees, and then he was off the Ralph train.
