If it wasn't for the Red card and the Penalty, would Man city be able to have altered the scoreline in their favour?

Second-half goals from Lionel Messi and Dani Alves were enough to give Barcelona a two-goal lead going into the second-leg of the Champions League last 16 at the Nou Camp after Martin Demichelis was sent off. The game's biggest incident happened just eight minutes after half-time, with the Argentine defender bringing down his fellow countryman just inside the penalty area. Messi slotted home for his first goal at a Premier League ground.
