Finnish commentator Oskari Saari predicts the chances of Kimi Raikkonen joining Red Bull for 2014 are "very likely".
The 2007 champion has been linked with Mark Webber's seat at Red Bull ever since the Australian's run-in with Vettel following the 'Multi-21' saga at the Malaysian Grand Prix.
The Finn was also very impressive early in the season scoring four podiums in the first five races, although Lotus and Raikkonen's form have slipped in recent races.
In Canada, Red Bull's Dr Helmut Marko said that all driver decisions for 2014 will be made during the summer break in August although that has not stopped the speculation continuing in the F1 paddock.
Also linked to Webber's seat is the Toro Rosso pair of Daniel Ricciardo and Jean-Eric Vergne. Aussie Ricciardo had strong races earlier in the season, but Vergne has put himself back in the frame with two good drives in Monaco and Montreal.
Despite that interest Saari believes Raikkonen remains a preferred choice for Red Bull:
"They're good guys, but not quite good enough," he told MTV3.
"I think the probability of Kimi going to Red Bull is very high -- it would be a logical move," added Saari.
Mark Webber is still not being ruled out to stay at Red Bull despite the difficult situation early in the season, earlier this month Christian Horner revealed talks will take place with Webber during the summer.
Should Raikkonen leave for Red Bull however, it is believes Lotus could turn to Pastor Maldonado and the millions in sponsorship he brings with PDVSA.
In other Red Bull news Italy's Autosprint is reporting the team could be using a type of illegal traction control after a photo emerged showing a pattern of rubber marks laid down by Webber's car consistent with traction control use.
"Bumps or traction control?" a report by Italy's Autosprint said.
The photo, which can be seen here was sent in by a reader who admitted the dotted rubber marks could also have been caused by the phenomenon of resonance in the rear suspension.
"Anyway, the image is worth reporting," the Autosprint story read.
