Reports had suggested that the Hungarian international midfielder had wanted to leave the club amid allegations of a falling out with manager Jim Magilton, who has been temporarily suspended by the club, at Watford on Monday night.
"It is not true at all," Buzsaky told the club's official website.
"I am entirely focused on our next fixture against West Bromwich Albion on Monday night.
"We are in a strong position just three points outside the play-off's and as professional footballers our sole aim is to focus on the upcoming matches."
