Mark Webber believes that former Red Bull teammate Sebastian Vettel will benefit after joining Ferrari for the 2015 season.
The four-time world champion moved to the Scuderia after six seasons at the Milton Keynes-based team.
However, Webber believes that the change of team may be a good thing for Vettel, who has impressed in pre-season testing for the Italian constructor.
He is quoted by the Herald Sun as saying: "Seb's not a silly guy and he realised that he needed fresh motivation and a new change and I think the decision was made very early, probably before the season even started, to be honest.
"The line is not 'they won't miss Vettel', the line is that when he wants to do something else and be in a different environment, then he is better off going somewhere he might feel he will get more out of himself.
"That's definitely a question for the team halfway through the season, whether they are missing some of that experience."
Webber raced for Red Bull until the end of the 2013 season, when he was replaced by fellow countryman Daniel Ricciardo.
