Tottenham are without a win in three games and travel the short distance across London to play Queens Park Rangers on Saturday.
Redknapp's side last won against Swansea on April 1, the last match to include a goal from Adebayor.
The former Togo international is clearly crucial to Tottenham's form.
In the five-game run without victory in the Premier League through February and March saw Adebayor score just once in the 5-2 defeat to Arsenal.
Saturday's London derby is crucial for Tottenham as they try to solidify their chances of playing in the UEFA Champions League next season.
Tottenham are fourth with 59 points in the Champions League qualifying spot, but fifth-placed Newcastle are only behind on goal difference and Chelsea are also close on 57 points.
Redknapp's side were thumped 5-1 by Chelsea in their FA Cup semi-final on Sunday and need the win both to keep their rivals at bay and to improve their morale.
QPR will also be desperate for victory as they try to stave off relegation.
Mark Hughes' side sit just above the relegation zone in 17th spot with 31 points.
Bolton are just two points behind, while Blackburn are also within touching distance on 28 points.
QPR's last game was a 1-0 loss away to West Bromwich.
Their last seven games have alternated between victory and defeat, with all wins coming at home.
That is a positive sign for Hughes as QPR have defeated Swansea, Arsenal and Liverpool in the last three matches on their home turf.
Hughes has Djibril Cisse available for selection again on Saturday with the Frenchman having served his four-match ban for a red card against Sunderland on March 24, his second sending off since joining QPR in the January transfer window.
While Cisse has played just five games since his transfer from Lazio, he has scored three goals in that time, ironically in the three matches in which he did not receive a red card.
If the flamboyant 30-year-old can maintain control, his undeniable quality and goal-scoring sense could be crucial to QPR's quest to avoid relegation.
