Portsmouth midfielder Hayden Mullins reckons they can upset Chelsea in the FA Cup thanks to their dressing room unrest.
Mullins insists there is no pressure on Pompey, still cash-strapped but now a modest mid-table Championship club.
Mullins said: "A draw or a loss for Chelsea against us will be a major disaster, especially the run they are on at home.
"The recent run is not like them but I'm sure they'll bounce back.
"The new manager is trying to put his ideas across and a few players want to leave. But as an outsider looking in it seems as though there is a little unrest in the camp.
"Even so we know that they are a quality side and we know what they can do, so it is still going to be tough for us.""There's no pressure on us whatsoever so we can go out and enjoy playing our game and hopefully getting a positive result.
