Tom Dillmann has secured a return to GP2 with new team Russian Time.
Russian Time chief Igor Mazepa believes securing Dillmann gives a squad a shot at the title in its debut year.
"His talent and experience will be key to our objective of taking Russian Time to the top of the standings this season," said Mazepa.
"I believe Tom can be a title contender this season. He has what it takes to win from the start."
Russian Time was created when Mazepa acquired iSport's GP2 squad last month. The team is run by Motopark Academy boss Timo Rumpfkeil.
Dillmann was a race-winner during a part-season with Rapax last year. He is sure Russian Time's resources will allow it to be a frontrunner from the outset.
"They are new to the series, but they have put everything in place to make sure that we are competitive from the start," he said.
"I hope that my experience in GP2 will help them even more. I am convinced that we can challenge the other teams and drivers for wins very quickly."
