Felipe Melo shouldn't even be playing professional football. He's so poor tactically that he really should be playing beach-football. Seriously. Especially his positioning, sucks. And that tendency to make those thoughtless, risky moves of his, never really left him.
One of the worst players to ever play for Juventus, in my opinion.
As for Vidal, well, he'll have everything to prove here, won't he? I totally agree with that. But will he surpass Felipe Melo? By miles.
Can't offer anything that Melo wasn't capable of?
Melo was a DM with no tactical sense whatsoever. He could be likened to a headless chicken. Vidal, on the contrary, is known for his tactical aptness. He plays the DM-role very effectively, and not only that, he can also go "box to box". Melo tried that as well, and apart from that goal he scored against Roma (away) in his debut season, almost always lost the ball while trying it. And on some of those occasions we conceded a goal. Last but not least, Vidal is a better passer. And as of yet, he doesn't kick opponents in the head, push people to the ground, talk shit about his fans and his teammates.
