Benitez shed light on why he had sanctioned a loan move to Czech side Slovan Liberec for Aarons.
He said, “When you analyse his position, we have Kenedy doing as well as he was last season, you still have Atsu, Ritchie and Murphy too, so to have a young player like Rolando he was not playing too much, afterwards he was injured.
“He needs to play, he needs to prove to himself and to everyone he is a good player for the future. He has the potential. He need a little consistency, he needs to play games in a row and that is the key for his confidence. He has played a couple of games, then on the bench, he needs to play."
