FIA has released the list of entries for this year's campaign including drivers with only three slots still open.

Toro Rosso are still looking for a team-mate to Seb Buemi and are believed to be waiting on whether Honda will make the grid as they are keen to sign Jenson Button.

However, should the Brit remain with his team, Takuma Sato and Seb Bourdais are the two most likely candidates to partner Buemi.

Honda, meanwhile, are still looking for a new buyer before announcing their line-up with Button, Bruno Senna and Rubens Barrichello all keen on racing for the new owners.
