Sheffield United vice-chairman Terry Robinson insists boss Neil Warnock will not be lured to Portsmouth.
Warnock has distanced himself from speculation that he is being lined up to replace under-fire Frenchman Alain Perrin at Fratton Park.
Robinson said: "We don't want to add to the speculation by commenting.
"We've had no contact from Neil about this issue because there's nothing to say. He's under contract and that's all there is to it."
Warnock refused to comment on reports he is set to replace Perrin.
The Blades are runaway leaders of the Championship and Warnock told BBC Sport: "I've got a job to do here."
Robinson said: "This story started back in October and it's dragged on since then.
"The club are highly delighted to have Neil as manager and we're happy with what he's doing.
"We expect there to be speculation over Neil because he is one of the best managers in the country.
"But he's more than happy to be at Sheffield United because he's a Blade. He's under contract, he's not going anywhere."
Pressure on Perrin, who took over last April, increased with Pompey's 2-0 home defeat to Wigan.
Perrin is eight months into the three-year contract he was given on taking over the reins from Velimir Zajec.
Pompey chairman Milan Mandaric, who is in America on business, may be tempted to make a change and move Perrin to the football director's role, vacated since Zajec's resignation on personal grounds last month.
Mandaric said: "Alain is a good coach but now is not the time for a professor, now is the time for a street-fighter."
Former Marseille boss Perrin is Pompey's eighth manager since Mandaric took control and managed to keep the club up last season but has he has won only four of his 19 Premiership games in charge.
