Manchester United executive vice-chairman Ed Woodward gave an emphatic no when Tottenham chief Daniel Levy asked about the possibility of signing Anthony Martial.
Spurs were keen on bringing Martial to London this summer and the Frenchman's agent was publicly pushing for United to let his client leave.
Martial has endured a strenuous relationship with Jose Mourinho and was believed to be keen on a new beginning.
The 22-year-old has turned the corner somewhat this season, coming up big on Saturday against Chelsea by scoring both goals in the 2-2 draw.
While reports have suggested Martial is still interested in leaving Old Trafford, the Manchester Evening News has reported Woodward was defiant when being propositioned by Levy in the summer.
United are reportedly desperate to hold to a player of Martial's talent, who they believe could become one of the best players in world football.
