A Formula 1 pundit has named the one mistake he believes stopped Daniel Ricciardo fighting for a drivers' championship.
The Australian appears to be done in the sport now, having been let go by Red Bull's junior team VCARB mid-season after being outperformed by Yuki Tsunoda.
Ricciardo first made his breakthrough at Toro Rosso back in 2012, before making the switch to Red Bull, where he would partner four-time world champion Sebastian Vettel.
Max Verstappen would soon replace the German, lining up alongside Ricciardo from 2016-2019.
Despite winning seven grands prix during his time at the Milton Keynes-based outfit, Ricciardo announced that he would be joining Renault for the 2019 campaign, a move which caught many by surprise.
And it was that transfer which F1 broadcaster Marc Priestley believes will always be a source of regret for the 35-year-old, who endured two disappointing campaigns with the French squad before moving on to McLaren where his struggles continued.
Speaking to Casino Uden Rofus, Priestley insisted Ricciardo could have won a world title had he decided to stay with Red Bull.
"Daniel Ricciardo could have absolutely won a world championship in his career," he said. "He certainly had the talent. Ricciardo was one of the only team-mates Max Verstappen had that showed some competition.
"It's a real shame how Ricciardo's career has panned out, the decision to join Renault and leave Red Bull was, in hindsight, the wrong move.
"Everyone hoped he'd become a world champion, he had the dedication, speed and great personality that you'd love a world champion to have."
