Fernando Alonso has admitted that he fears that his Ferrari does not possess the pace he needs to fight through the field at the Korean Grand Prix to keep his title hopes alive.
The Spaniard currently lies 60 points behind Sebastian Vettel in the drivers' standings with the Red Bull man on pole for Sunday's race.
He told Autosport: "In the race pace yesterday we saw some problems, so I'm a little bit less optimistic in terms of winning the race or a podium finish for tomorrow.
"There's always some action in this race so we'll see what we can do, but we know that we'll also struggle tomorrow."
Alonso will start the Korean Grand Prix from fifth on the grid.
