Dunno, I might be wrong. I rarely see players leaving from one league to another. And whenever I see games they are just too different, different style and everything.
But maybe, I have no idea. To me it looks like two different worlds. And I'm not saying PL is better or harder based on that. To me PL was always about higher paced players with less brain -- Pepe like -- who carry the league. I think even Mourinho said there's much more brain involved in Serie A.
