Gus Poyet has said he will not stay at Sunderland if director of football Roberto De Fanti signs players without his approval in January.
This threat will not be welcome to Sunderland fans, who had hoped that Poyet would bring some stability to the club in the wake of Paolo Di Canio's turbulent time in charge at the club.
Poyet has been in charge for only six weeks, leading his side to a win in the Tyne/Wear derby, but has stated he will not stay at the club if he does not get the final say in transfer policy.
Di Canio made a number of signings over the summer, with some questioning whether director of football De Fanti was the one who had the final decision on some of them.
Speaking ahead of Sunderland's match against Stoke this weekend, Poyet said, "We talked about a position the other day and considered four players. I picked two. It was simple. One of the other two (selected by De Fanti) was a definite no.
"If that one is coming, I won't be here. The player has to be the right one for me. If not, I'm not going to accept it."
"They need to give me the options and I need to pick the ones I like. We need to see if they are available and if they fit into the financial possibilities, then we will move forward.
"I'm sure it's going to be done in the right way, in the common sense way. Everyone has a responsibility."
Despite such comments, Poyet is generally happy with a working arrangement which he admits is unusual for British football.
Poyet was also quick to make the point that he is happy at Sunderland however, and commented on the position of a director of football in the English game, where there are far fewer compared to on the continent.
"The sporting director exists everywhere in the world," he said. "I know in England it's not very common. The manager is normally in charge of everything but I had it at Zaragoza as a player and my situation is clear."
"So far, everything is working fine. The connection and communication have been great."
"The idea is to start moving. The sooner we move, the sooner we get a player, the better for me."
With Sunderland currently fighting a relegation battle, fans will be hoping that any new signings in January will aid their fight for survival, rather than forcing their new manager out the door.
