We can take full advantage in this game that Barcelona will come with a sense of arrogance and self belief that they can win this one easily at home. I think we have to setup to hassle them, press and really bring out our qualities, we did the first 2 in the home leg but the 2nd I think we struggled to do. The most important thing is an early goal because if we get something early, they will crumble defensively, it wouldn't be the first time. I think they found it easy to deal with Negredo who we tried to push the ball upto him on his own, this time we'll have a completely different threat in having Aguero just over the shoulder of Pique who is slow as hell. Mascherano also isn't the best player positionally and in some parts their defence was all over the place when we attacked, see the Negredo chance in the first half when he flicked it over their keeper, where their players get pulled all over the place and Aguero is more mobile and can quickly exploit that.
Whether it would be suicide to play with both Negredo and Aguero I don't know but I think Barcelona will have a completely different level of problems to deal with in Aguero which they didn't really have consistently in the first leg. That first 30 minutes before Aguero got injured against Spurs away was one of the most devastating attacking efforts I've ever seen individually and if he's playing at that level despite their possession they'll be scared stiff of him dropping deep for the ball in that pocket of space where Busquets plays on his own. I can see us getting a goal or 2 and I also can see us keeping them out because they never threatened us on Tuesday, it took a penalty and a sending off to give them the space they needed. I thought Messi may as well of not bothered turning up because he was never given the time or space and he was still then playing against Kompany who read him like a book.
It is still going to take some effort where we need our best ever performance as a team, without any mistakes but I think we can get a good result at the Nou Camp, having Aguero back is going to really cause them problems. Negredo is fantastic but Aguero cannot be marked so easily and half the chances we had in the home leg I have no doubt Aguero would of put away.
