Newcastle United's players are involved in another bonus dispute with the club.
The Gazette reported on a bonus dispute last summer.
Twelve months later, the players are yet to agree to a bonus scheme for the coming Premier League campaign.
Newcastle's players refused to speak to journalists after last night's 4-0 defeat to Braga.
Captain Jamaal Lascelles informed the media that the squad would not be talking in the mixed zone.
Their refusal to do interviews is understood to relate to the bonus dispute.
Asked about the players refusal to speak, United manager Benitez said: "When things are not going well off the pitch, you can see a reflection."
The new Premier League campaign kicks off on August 11.
