Harry Redknapp does not know whether he will be allowed to keep Emmanuel Adebayor at Tottenham beyond the end of the season.
When Adebayor arrived at White Hart Lane on loan from Manchester City last summer, there were serious doubts about his temperament, but he has defied the critics to become a key player for Spurs.
The Togo striker has scored 14 goals and his physical presence up front has allowed the likes of Rafael van der Vaart, Gareth Bale and Luka Modric to prosper in midfield.
The 28-year-old wants to stay, but his reported wage packet of £170,000 a week will prove to be a big stumbling block. Redknapp would love to keep the former Arsenal striker, but is unsure whether a deal can be agreed.
The Tottenham manager said: "He scored two goals last week against Swansea and he has been excellent, but whether it's possible to do a deal, I wouldn't be sure.
"Manu is on loan at the moment and that's where we're at.
"The chairman will deal with (any negotiations) at the end of this season. I wouldn't have a clue whether (a permanent transfer) is a possibility or not."
Critics have claimed that City, who now trail Barclays Premier League leaders Manchester United by five points, made a mistake in letting Adebayor go, despite his previous troubles with Blues boss Roberto Mancini.
Reports claim some of City's players want Adebayor back at the Etihad Stadium next season, but Redknapp doubts that will happen.
"His future doesn't seem to be there," Redknapp added. "He probably needs to move on. City have just gone through a dicky little spell recently but they have lots of good strikers there."
