He's made for this league. He's not foreign.
When a player has loads of pace, good dribbling skills and scores goals due to fantastic shooting technique, he can fit in any league.
I can imagine Real would like to buy him like all top clubs.
But I don't really think being Ronaldo's understudy is the career path Bale or his agent would want to take.
Why would he be Ronaldo' understudy? You think Real offered those prices for a 2nd string player?
