Ferrari's Fernando Alonso is "happy" with his performance in the Korean Grand Prix despite coming third in the race.

The Spaniard is now six points behind Red Bull's Sebastian Vettel in second place in the drivers' championship, but he noted that Ferrari are ahead of McLaren in the Constructors' Championship.

"We have to be happy with the performance today," he said. "We finished third and fourth behind the Red Bulls who are difficult to beat.

"It was a good day for team, for me and for Felipe, and we overtook McLaren in the Constructors' Championship so we are moving in the right direction. We just need an extra step to be as competitive as Red Bull."

There are four more races left this season.
