Tano is a big fan of the Valencia playmaker, who he feels possesses the wit and creativity to dictate play and unlock defences. He adds that he hopes Gabriel Batistuta wins a starting place and expects big things from Aimar's club mate Kily Gonzalez.
"I don't know how they are going to play because they tend to change a few players," said Tano.
"I think Aimar will be key, I hope Batistuta is playing but, saying that, Crespo is a great striker also.
"I like Aimar a lot. He is a great player on the ball and tends to create things and is quite sharp. I think he could be the one, but I don't know if he will have a place in the starting eleven.
"Then you have to go with, I think, Kily Gonzales on the left. He's sharp, quick and aggressive - he could be an important player."
Mauricio Taricco admits second guessing Argentina coach Marcelo Bielsa's starting line-up is not easy, but predicts Pablo Aimar will make a big impression at the World Cup.
