Manchester United, Manchester City and Chelsea have all reportedly been keeping tabs on Jamie Vardy's contract situation at Leicester City.
The striker, who is believed to earn £40,000 a week, is contracted to the King Power Stadium until the summer of 2018.
However, according to Sky Sports News, talks over fresh terms are yet to get underway, despite Vardy's positive form in front of goal this season.
The report adds that the supposed uncertainty over the 28-year-old's future has captured the attention of the three Premier League heavyweights, all of whom have asked to be kept informed of any developments.
Vardy is the division's joint leading goalscorer along with Everton frontman Romelu Lukaku, having found the net 15 times.
