Napoli have had a €37 million offer accepted by Real for the Argentina international and are now thrashing out personal terms.
Tavano told TMW: "He would be a big hit if he was signed up as it seems. I think the guy can do really well for Napoli.
"He’s a striker, even a football player, more complete than Cavani. They will not regret losing him.
"I think he can turn Napoli into a different team."
