Aldo CostaAldo Costa looks set to make a return to Formula 1 with Mercedes GP, having left Ferrari earlier this year as part of a staffing reshuffle.

The Italian was dropped as technical director of Ferrari in May after a disappointing start to the season, and it was announced in July that rather than move to another position in the company he would be leaving the team. Speculation has now suggested that Costa could renew his links with Mercedes GP team principal Ross Brawn, with the pair having worked closely together at Ferrari in the past.

The suggestions of a tie-up grew at Monza on Thursday when Brawn did not deny that Costa could be on his way to the team. Asked about prospects for Costa joining the team, Brawn paused before saying: "We don't comment on our structure, as you know."
