The 27-year-old Togolese striker arrived in north London from Premier League rivals Manchester City, and has impressed for Harry Redknapp's side by netting ten goals so far this term.
The main sticking point over a permanent deal to keep Adebayor at White Hart Lane is his high financial demands - at present City pay around £105,000 of the Spurs striker’s £175,000-a-week wages.
Tottenham's current top earners collect in the region of £70,000-a-week, but that wage structure will likely be broken if the club returns to the Champions League next season, as Redknapp looks to further strengthen his squad for another crack at Europe's top table.
Adebayor is keen to remain in the capital, but his long-term future may be dependent on whether or not Redknapp - who was instrumental in signing him in the first place - stays at Tottenham, with the 64-year-old the bookies' favourite to become the next England manager.
With only one year to run on his City contract, the African striker looks set to leave the Etihad Stadium permanently at the end of the campaign, whether or not that will be to Tottenham remains to be seen.
