Toro Rosso has fuelled rumours that Sebastien Buemi could be set for a surprise return to the team as the Italian outfit looks to replace the departing Pierre Gasly.
The team posted a photo of the 2015-16 Formula E champion undergoing a seat fitting, captioned: "Ciao Seb! Our reserve driver stopped by earlier today for another seat fit."
Whilst it's not unusual for a reserve driver to undergo a seat fitting, it's often something that takes place before the season has begun, whilst a second fitting in the same chassis isn't so common and some would say unnecessary, unless a driver has drastically changed shape/weight.
Also, given it's happening at a time when the 2018 'silly season' is very much in full swing and Toro Rosso are hunting for a replacement to partner Brendon Hartley – or maybe even two drivers for an all-new line-up given Hartley's underperformance – and with limited options available after Lando Norris, a prime target for Red Bull, was announced at McLaren, Buemi is certainly a contender for the vacant seat.

Whilst it could well be an innocent photo, it adds to speculation as to just who might be announced at the Red Bull junior team, with only a handful of names being mentioned alongside Buemi's, including Daniil Kvyat and the recently available Stoffel Vandoorne.
