"Negredo is someone I've played against - he's a good striker," the Argentina international said. "A typical number nine. I'd say he is similar to Edin Dzeko, a tall player.
"He works very well inside the box or drops deep to receive the ball when he has to."
"If he's the one we bring in then it will be because the manager has 100 per cent confidence about him and I would expect him to do well."
