ABU DHABI, United Arab Emirates – Former champion Jenson Button's future remains uncertain, and his fifth-place finish at Sunday's Abu Dhabi Grand Prix could yet prove to be his final race in a distinguished Formula One career.

Button faces an anxious wait before McLaren announces its driver lineup for 2015 early next month, with two-time F1 champion Fernando Alonso widely touted to replace him after leaving Ferrari.

The 34-year-old British driver won the title with Brawn in 2009 and finished runner-up to Sebastian Vettel in 2011.

Alonso is being tipped to drive alongside 22-year-old Danish driver Kevin Magnussen at McLaren, even though Button outscored Magnussen in points 126-55 this season, with both drivers getting one podium place each.

Magnussen finished the Abu Dhabi GP out of the points in 11th spot.
