Among those targeted by Benitez to bolster his striking ranks is Arsenal outcast Perez, who has so far been priced out of a move away from North London despite plenty of interest.
It has been reported that the Gunners are holding out for around £14m for the Spaniard, but Newcastle would rather take the player on loan as they are seemingly short on cash.
Outlining discussions he has held with Wenger, Benitez told reporters: "I said: 'Listen, we have to talk.' And he said: 'Do you have some money?' Obviously, we like good players, but it's too soon to talk about that."
Fenerbahce and former club Deportivo La Coruna are the other two clubs understood to be in the running to sign Perez, who was restricted to just the one start in his maiden Premier League campaign.
