"I think he did okay," said Benitez about Insua.
"These kind of games are difficult to come into but against a player with experience he was good. I told him not to go forward so much as we have Ryan Babel on the left, who is a very offensive player.
"But when he did go forward he was good and it is one of his main attributes. Today he was good in defence, worked hard and showed quality on the ball.
"We have some players very close to the first team. They will need more experience but at least you know you can use them if you need to and Insua is one of these players."
