The former Arsenal teammates will face eachother this weekend and Pires said: "On the field he has a special behavior. He is brilliant like Eto'o or Drogba and I believe that he can finish the top scorer in the Liga without problems.
"Though on Saturday he won't score (laughter), but he has everything to be 'pichichi'.
"He knows that he is not at 100 per cent, but is doing well at 80 per cent. And with that already he is dangerous. He was injured almost six months, he has changed Leagues and has gone to a team with great expectations, but he has adjusted well."
