Sebastian Vettel and Daniel Ricciardo have both been criticised by a former Red Bull star during a discussion about their Formula 1 careers.
The pair enjoyed success at the current constructors' champions, and were team-mates during the 2014 season, with the Australian finishing two places ahead of his more experienced colleague in the drivers' standings.
Vettel enjoyed a stellar career with the Milton Keynes-based outfit, winning four consecutive titles between 2010-2013, before going on to enjoy less successful periods at Ferrari and Aston Martin.
Ricciardo, meanwhile, was touted as a potential world champion during his five years spent at Red Bull during the early stages of his career, but subsequent moves to Renault and McLaren put paid to any title ambitions.
Speaking to Motorsport.com, former Red Bull racer David Coulthard reflected on the duo's careers as he discussed the team's greatest-ever drivers, before selecting his top three.
Despite Vettel holding the upper hand - for now - over Verstappen in terms of championship wins, the German was pipped to the top spot, while Ricciardo was surprisingly omitted from the list altogether.
When asked to name his all-time Red Bull top three, the Scotsman joked: "That has to be Max, Max and Max.
"You can't take anything away from Seb's four world titles, but if you look at his career as a whole, Seb was no longer as impressive at the end as when he won his world titles.
"Look at Michael Schumacher at Mercedes - he was also no longer as impressive in that period as he was in his Ferrari time.
"It shows that everyone has their own time, but I think it is obvious to put Max first... Seb is second with his four world titles.
"As for P3, I would say Mark Webber ahead of Daniel Ricciardo, because he was a more 'manly man' and Daniel a bit more of a 'boy man', so to speak.
"The latter is partly due to the fact that Webber did not let anyone walk all over him.
"Moreover... he had to compete with the then world champion for years, while Ricciardo preferred a lucrative departure to Renault to fighting with a Verstappen on the rise."
