Fernando Alonso went quickest in third practice for the Singapore Grand Prix as he mirrored his performance from first practice on Friday.

Red Bull's Daniel Ricciardo was just pipped to the top and came second, while Mercedes Nico Rosberg completed the top three.

Lewis Hamilton was unable to capitalise on his second-practice performance as he finished sixth and looked to have had problems with his car, drifting several times.

Jean-Eric Vergne clocked in at fourth, with reigning champion Sebastian Vettel finishing in fifth.

All eyes will be on the two Mercedes in qualifying as a good starting position on the grid will almost guarantee points on such a tight circuit.
