Three-time World Touring Car champion Jose Maria Lopez paid tribute to Citroen for "relaunching my career" ahead of his championship farewell in Qatar next week
The Argentinian was hired by Citroen for its series debut in 2014, alongside nine-time World Rally champion Sebastien Loeb and Yvan Muller, the most successful driver in the modern iteration of the WTCC.
Prior to that, GP2 race winner Lopez had been forced to pause his international career and return to South America - where he won the Super TC2000 title in 2012 - after his European prospects dried up, with an failed attempt to make it to Formula 1 with the proposed USF1 team particularly damaging.
Lopez then caught Citroen's eye in a one-off 2013 WTCC appearance at Termas de Rio Hondo, winning the second race in a Wiechers-Sport BMW.
The 33-year-old has since dominated in his three years in the WTCC, and clinched his third title with Citroen at Motegi in September.
The Frenchman, who was involved in developing Citroen's C-Elysee ahead of its first campaign in 2014, said his final weekend would be a poignant one.
"Everyone is telling me it will be a special race and I'm beginning to realise it will be a really emotional moment," said Muller, who is currently second in the points ahead of Honda's Tiago Monteiro.
"This is not only the end of my career, but the end of a great adventure with Citroen too.
"I was there from the start, which is something that hasn't often been the case in my career, and I'm proud of what we have achieved.
"I haven't won any titles myself, but collectively we have had a lot of success; I'm touched by the gratitude the Citroen Racing team have expressed to me.
"On Saturday morning, I'll be starting a new life.
"I have been lucky enough to choose when I stopped and I'm going to enjoy my first winter off in decades."
