Aldo 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 on the back of 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.
And 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.
When asked by AUTOSPORT about Costa joining the team, Brawn paused before saying: "We don't comment on our structure, as you know."
When pushed about whether someone like Costa would be a good addition to the outfit as it bids to get back to winning ways, Brawn said: "We don't comment on our organisation."
