The Belgium hitman has shone in what has been a difficult season for Villa as they battle against the drop, and this has brought him to the attention of would-be suitors.
As well as Spurs, Manchester City and Inter Milan are also thought to be interested and that list is likely to grow at the end of the season.
Much will depend on Villa's battle to beat the drop. If they win it, then he may stay in the Midlands, but if they lose it then he will be on his way.
Spurs have a need for new strikers as Emmanuel Adebayor has had a poor season, with reports suggesting he exit at the end of the campaign and that would leave Jermain Defoe as the only out-and-out front man in the first team.
