You have to understand that Queresma was pretty damn young at that time. It's not easy to break into such a talented team when you are so young.
I still don't know if he's the right player for them. I think they have plenty of flair and skill on their team. They now need someone who can do the dirty work. A player like Essien would be ideal for them.
I also think they need a bigger man in the box. They need someone who the wingers can cross the ball to. If you watch any of the Barcelona games, you'll notice that they barely cross the ball. They go down the flanks but then they pass the ball back inside rather than putting it in the box. They need some variety and a bigger striker could give them more attacking options.
