“These sort of stories always tend to come out during an international week,” said Benitez to Liverpool’s official website.
“I was talking with Martin at Melwood yesterday and it was clear that he is very happy and just wants to get back playing.
“He is working very hard to get himself fit again and he is very settled at Liverpool – both in the city and at the club.”
