Chris Boardman believes Mark Cavendish would be "crazy" to not take Mark Renshaw with him to his next team.
Renshaw was Cavendish's lead-out man as the Manxman won five stages of this year's Tour de France for HTC-Highroad.
"It would be absolutely crazy for him to not take at least Renshaw," Boardman told BBC Radio Merseyside.
"Cavendish on his own is still a formidable sprinter but he would not have had the volume of wins without the team behind him."
Cavendish, 26, has always publicly backed and thanked his team-mates for the work they do in helping him record race wins.
He is known to be particularly close to Bernhard Eisel and Boardman believes the trio should move together when HTC-Highroad disband at the end of the season.
"(He should take) probably Renshaw and Eisel because there was a number of stages he won in this year's Tour de France and credit to him he praised his team and knew they put him in the right position.
"Wherever he goes he'd be foolish not to take those people with him," said Boardman.
"We've seen other sprinters like Andre Greipel leave the HTC set-up and the number of their wins drops dramatically."
Cavendish has been heavily tipped to join fellow Briton Bradley Wiggins at Team Sky.
Boardman, a former wearer of the yellow jersey on the Tour de France, says if they do link up it will be interesting to see how they balance Cavendish's needs as a sprinter with Wiggins goal of making the podium at the Tour.
"Sky proved to me, with Bradley Wiggins this year, that they've got a genuine Tour podium contender, even for the top spot.
"How do you split your resources between those two places?" said Boardman.
"I just don't know but maybe we're going to find out next year."
