Inter are expected to buy a new striker in January.
"We have strong attackers," he told Sky Sport Italia. "I don't think we have any problems in that area of the pitch.
"In fact, I'd say we have the best attack in the League. But this sort of decision should be left to the Coach and the club."
The Argentine goalscorer then commented on the Nerazzurri's upcoming match with Sampdoria.
"We're not looking at the League table at the moment. We just want to play them and win, that's all.
"We're going to have to go game-by-game, and if we continue like this then we can get to the top."
