Coulibaly was tipped for great things as a teenager, but he has failed to live up to his early promise and he is now looking for a new club.
The Ivorian has spent time at Spurs and, more recently, in Italy, but he has never settled and is now looking for a more permanent home.
QPR feel that Loftus Road could be the perfect place for the striker, as he fits in well with what they are trying to achieve next season.
The R's are attempting to freshen up their squad by bringing in a number of promising youngsters, as they look to make an immediate return to the Premier League following their relegation to the Championship.
The signing of Coulibaly would be a signal of their intent and he could be a bargain buy, if he does start to live up to his promise.
The 20-year-old still has plenty of time to develop and he could be worth taking a gamble on for the London club.
