I wouldn't mind the Filipe Luis signing but using "he's played against Ronaldo, Bale, Di Maria and Pedro" as an argument as to why we should sign him is very poor. Using the "can he cut it out in Europe?" argument in conjunction to that is poor as well. Not every right winger in Europe is Bale/Di Maria/Pedro level... Sure, Luis is a top left back, one of the best in Spain, but Shaw based on current ability is also one of the best in his position already in the PL too. Shaw plays beyond his years already. On average, the jump from PL to CL isn't even that big because you don't face the best of the best every game. You're really reaching if you're trying to use European experience as a reason not to sign Shaw IMO.
