The former Blackburn centre-back has been criticised since joining the relegation-threatened London club on a reported £100,000-per-week deal from Anzhi Makhachkala
The Congo-born centre-back reportedly signed a £100,000-per-week deal with the Rs upon his arrival from Russian club Anzhi Makhachkala two months ago.
However, the 28-year-old claims that his return to England came about because of his desire to be close to his children.
"The owner is investing so much into this club, it's going places and you'd have to be crazy to leave," he told Sky Sports, while referring to Anzhi.
"I had three years left there on a big salary. Obviously, going to QPR is not to make more money. Not at all. All the talk about money is just nonsense.
"I missed my family and wanted to be back with my boys. All the money in the world cannot make you the happiest man.
"I think for your life to be complete you need to have two sides. If you can enjoy your football and have your loved ones close with you - that's all you want."
