The 22-year old French-born Senegal international has appeared six times for the Râ€™s since joining permanently from Arsenal in the summer and he feels that each week he is showing plenty of improvement.
"I am very happy with how I have played so far but for me it is important to play well each week,â€ť he told the clubâ€™s official website.
"I am focused on the next game, not what I have done in the past.
"This is the first time since I was 17 that I am playing every week, and this means a lot to me," he added. "It is helping me to develop each week."
