#3 Daniil Kvyat
That's right, Daniil Kvyat is back on the Toro Rosso scene after taking a season out of the F1 driver's line-up. The Russian spent most of last year as a reserve driver for Scuderia Ferrari behind Sebastian Vettel and Kimi Raikkonen.
With Pierre Gasly's promising talent promoting him to Red Bull and Brendon Hartley not convincing Dr Helmut Marko to keep the New Zealander on board for another year, Kvyat was called back in.
It looked as though Kvyat would never return to the F1 grid - but he might have to thank former teammate Daniel Ricciardo for shockingly departing Red Bull - bringing the opportunity back to the Russian.
The 24-year-old left Toro Rosso before the 2017 championship had even come to a close.
Kvyat may only have the upcoming season to prove himself but his past experience in F1 may help Toro Rosso be a threat at the mid-table point of the constructors' championship.
