Jonathan Rea could lift his consecutive World Superbikes titles today at Jerez but he needs a 50-point lead over Kawasaki team-mate Tom Sykes to do it.

Here are the scenarios for a double world champ:

• Rea wins the race and Sykes finishes third or lower
• Rea finishes second with Sykes fourth or lower
• Rea finishes third with Sykes sixth or lower (with a 50-point gap, Rea would be champion with more race wins)
• Rea finishes fourth with Sykes ninth or lower
• Rea finishes fifth with Sykes 11th or lower
• Rea finishes sixth with Sykes 12th or lower
• Rea finishes seventh with Sykes 13th or lower
• Rea finishes eighth with Sykes 14th or lower
• Rea finishes ninth with Sykes 15th or lower
• Rea finishes tenth and Sykes does not score points

The Castletown resident said yesterday that he didn’t think it would be possible to win as both Sykes and race one winner Chaz Davies had better pace. Rea finished this morning’s warm-up in fourth place, half a second slower than Sykes.
