Recent reports indicate that the veteran midfielder is on the verge of exiting the Stamford Bridge doors after told he would not be getting a new deal with the Blues but Benitez played coy on the situation when quizzed after Wednesday's 1-0 win at Carrow Road.
"We don't talk about speculation, that is a conversation between Frank and the club," said Benitez.
"We have to do our job which is to try and prepare the team for the next game.
"To be fair I do not pay too much attention [to the rumours] because I have to concentrate on the games.
"Some things in the newspapers is something every club has to manage with."
