In 2007 he became the youngest ever driver to compete in the FIAWorld Touring Car Championship. He competed in two rounds at Oschersleben for GR Asia in a SEAT León, after impressing in the German SEAT Leon Supercopa. An encouraging debut saw him finish thirteenth in race one, and nineteenth in the second race. For the next event at Brands Hatch, Sadredinov was also due to race. Problems with his passport for getting into the United Kingdom meant he was replaced by fellow Russian driver Sergey Krylov.
