Paul di Resta is poised for a new role in Formula 1, amid mounting speculation that he will be announced as the reserve driver at Williams this week.
The Briton has spent recent years focusing on a DTM programme after being dropped by Force India at the end of 2013.
He made his debut for the outfit in 2011, scoring in his first race for the team in Australia and going on to perform well over the subsequent three seasons.
But after losing his place for 2014 to Sergio Perez, di Resta was unable to find another drive in F1 so returned to Mercedes' DTM squad, with which he had won the championship title in 2010.
With the Scotsman having never given up on chasing F1 opportunities, di Resta's fresh chance appears to have come up thanks to Williams' need to find an experienced driver to replace its previous reserve Adrian Sutil.
A report on the BBC on Sunday said that the di Resta-Williams deal was done - and that he would travel to races with the team and be called upon to race if Valtteri Bottas or Felipe Massa cannot compete.
Last year, Bottas had to sit out the Australian GP because of back problems - and his Williams FW37 did not take the start.
Williams declined to comment on the situation when contacted by Motorsport.com, but it is understood an announcement confirming its plans will be made before the Australian Grand Prix event gets under way.
