Thats why I´m skeptical about Neymar playing at Barca. You said yourself that Barca would need almost 90% possession so both Messi and Neymar have the ball enough to be as effective as they can be, which is insane, an average of 90% is impossible, even for this team. Neymar coming into the first 11 would mean Messi gets less time on the ball, as the midfield will still need their share of possession to control the game. And taking away time on the ball from the greatest player in the world is nothing but a step backwards. Neymar may be talented, but he´d have to adapt his game to from a playmaker to a pure winger or finisher, but we have other people for these jobs already (well, we could use a finisher, but hopefully Villa will get more playing time soon). And we´ve all seen what can happen to a playmaker that is forced to play as a winger in Alexis, they´re just not the same anymore.
