Over and over, I've heard Alexis excused for his poor offensive play because of his "defense, workrate, width, runs," and so forth. Going by this silly logic, Barca ought to play with four fullbacks (for instance, Alba and Montoya in defense, Adriano and Alves forward). After all, I'm sure the fullbacks are even better defenders than Alexis, they have plenty of work rate, they'll be disciplined and keep width, and do everything Alexis is praised for. Sure, they might not be able to score (actually, they'd probably be better than Alexis) but according to some that doesn't matter.
