Regarding Messi dependency.. Messi is involved in 46% of Barca's goals, compared to Ibra (51%), Falcao (49%), Suarez (48%).
While obviously that doesn't tell the whole story since that number is very significant and besides that the system revolves around Messi, but Barca is far from the only team in Europe that built a system around one player.
Interesting. And it should be borne in mind that Barcelona scores more total goals than those other players' teams, so there are A LOT more non-Messi goals than non-Ibra/Falcao/Suarez goals.

The only 2 spots where messi will struggle is as a center back, And a goal keeper.
Messi is amazing at retrieving balls, And keeping possession, The only qualities of DM that he lacks is 'tackling' and areal ability, Although i'm not sure about the tackling thing, Other wise he's great, Plus I stated DM, LB and RB separately from others, meaning that he'll be a bit less good from the other spotsAll right, that's too much. Messi as a defensive midfielder?
He will age better then C Ronaldo who relies on his pace and physical attributes
