The Brazilian midfielder feels that Defoe could bring a lot to the team, having played with him previously at Tottenham Hotspur, and hopes that the rumours of the R's interest in the experienced forward are true.
However, at this stage of his career there must be concerns over whether Defoe is capable of performing in the Premier League.
A lethal finisher in his day, Defoe is unlikely to have lost this quality, but his pace and mobility have decreased as the years have gone by.
The 32-year-old has been playing his football in the MLS for nearly 12 months now and would likely need some time to adjust to the Premier League again if he did come back to England.
It means that Defoe's arrival at QPR may not be one which they should pursue, despite Sandro's craving for a reunion with the England international, and in this piece we take a look at three strikers who could be better options.
Danny Ings (Burnley)
Danny Ings' contract at Burnley expires next summer and the Clarets are unlikely to be wanting to lose him on a free.
He could, therefore, be available at a cut-price in the new year and would enhance the quality that Redknapp has available to him.
Ings is only 22-years-old and has not fully adapted to the Premier League yet, but he is the sort of player who could form a lethal partnership with Charlie Austin up-front.
The England youth-international is tireless in his work-rate and enjoys playing on the shoulder of the last man, meaning he could benefit from Austin's more physical approach.
Ings is a striker who is likely to develop in the future and if Redknapp is thinking long-term than he is a far better buy than Defoe would be.
Andre Ayew (Marseille)
Another forward whose contract is expiring at the end of the season, Andre Ayew could be a viable target for the London club to pursue in January.
Ayew should not have a problem coping with the demands of the Premier League, due to his physical attributes and he would provide Redknapp with a different sort of option to what he currently has in his forward ranks.
At 24, Ayew should just be starting to head into his prime and he represents a potential bargain.
Joel Campbell (Arsenal)
The most expensive of the three possible options, Campbell could be tempted to join QPR due to the offer of first-team football.
The Costa Rican was in fine form at the World Cup, but he has failed to make an impression back at the Emirates Stadium and a move could be an option in January.
Campbell can play either as a striker or a winger and his speed is his major weapon, although he also possesses a clinical touch in-front of goal.
Another player who still has plenty of time to develop, at 22, he would surely make a better purchase than Defoe for Redknapp's men, or could even be available on loan.
