Please, please, please let's sign Sergio Aguero....
In addition to his two goals last night, he provided the centre from the corner that was headed on to the bar in the first half; he worked incessantly; he demonstated his dribbling ability; and he combined well with Messi, in particular.
His clinical second goal was set up by a beautiful through ball from Messi. I particularly appreciated the way Aguero pointed at Messi to say that the goal was really 'his'. I don't recall Tevez ever doing anything like that.
