Babel has failed to make a impact at Anfield since joining the club from Ajax in 2007.
“He’s improving and he’s working hard and trying to learn and have a proper understanding of the Premier League, and hopefully we will see the best of Babel this year,” said Benitez in the Daily Express.
“But he is still a young player and he needs to change some things and he will be better.
“He knows that sometimes he can be a very good player for us and he is trying.”
