Yes, but I always preferred him on the right, based on the few games he did there. In the left flank he tend to cut too much inside, so when he is on the right at least he can easily shoot with his best foot.
I thought you would say AM, though, because I believe he could perform very well in Pablito's role. The only bad thing about it is that I do not see Gaitan managing the tempo for the whole team like Aimar does.
