Chelsea boss Rafa Benitez was happy to give Marko Marin some action in defeat at West Ham United.
Benitez admits he's a fan of the German.
"I knew Marin when he was at Werder Bremen, Liverpool played against them and he was one of the best players," said Benitez.
"Watching him in the training sessions here he seems sharp, and you can see that he's very clever. He's keen to learn and he's not someone you have to explain the same thing to three times. He's someone that can help."
