Burton has risen to fourth in the world rankings following a string of consistent displays, which saw him claim a place on the podium at both the World and European Championships earlier this year.
Roux feels the 31-year-old is leading by example as Team GB continue their quest towards delivering medals at London 2012. "The highlight of Euan is his consistency. We're all very impressed with him," said the Frenchman. "He is delivering at major events. Also important is the style of his performances and he is continuing to improve in that respect. Euan has a good spirit and a fantastic attitude."
Roux, a former European champion and world bronze medallist, has overseen the introduction of a new centralised training centre at Dartford for the elite athletes as part of a development plan for the sport, aimed to peak when the Olympics come to Britain - with judo targeting at least three medals.
With several youngsters showing promise, Roux hopes 2011 will prove another key year for Team GB's Olympic hopefuls. "Gemma Howell and Gemma Gibbons showed that they have connected at this level and are showing consistency," he added.
