"Albert and Ryan both want to play. They play in the same position and so have to compete with each other, which is good for us," said Benitez.
"The message is very simple. On the pitch all of the players have to prove something.
"Ryan knows he cannot go now, so he has to impress. He is a good player and we know he has talent. It's important for us to talk with him and see how he progresses over these months.
"With the World Cup at the end of the year the majority of our players will want to impress and if they do well in each training session they will have more chances."
