Jose Mourinho has angered BT Sport's bosses by making an impromptu appearance on Sky Sports' show 'Goals on Sunday'.
The Chelsea manager - who signed a three-year deal to become a BT Sport ambassador in July 2014 - gave a lengthy and controversial interview to Sky following his side's 1-1 draw with Burnley.
Back in January, BT bosses were delighted by his refusal to speak to the Sky cameras following Chelsea's televised game against Manchester City.
But following Mourinho's astonishing 27-minute rant on Sky Sports last weekend, the self-proclaimed 'Special One' finds himself firmly in BT's naughty corner.
As reported by the Telegraph, BT bosses have been closely studying their contract with the 52-year-old to see if he was in breach by appearing on 'Goals on Sunday' without consent.
The news provider says representatives for the Portuguese manager have defended his appearance on the show.
They argue that he did not need prior approval, as the interview was carried out as part of his duties as Chelsea manager.
It remains to be seen whether BT chooses to take any further action against Mourinho, or simply looks to clarify the scope of his ambassadorial role.
