Benitez is still looking to loan out Aarons and Jamie Sterry before the month is out - even though the Magpies have limited cover at full-back.
“Rolando is one of these young players who needs to play, and Sterry is another one who we can allow to go on loan because they need minutes," Benitez said.
“They need to play. Rolando is more of a winger and we can manage the situation at left-full-back with the other players we have here; with Clark or Kenedy, which is why Sterry can go.
“Still we have [Christian] Atsu, [Jacob] Murphy and [Matt] Ritchie, so we have some wingers. We don't have another specialist left-back, but we can manage the situation."
