Fernando Alonso will be in top physical shape for years to come, according to his trainer.

After his mysterious Barcelona testing crash and hospitalisation, the Spanish driver admitted he was not fully fit when he returned to the wheel in Malaysia.

Following China, 33-year-old Alonso flew to Dubai - where he lives - to train hard ahead of this weekend's race in Bahrain.

"At the moment we are training more than four hours a day," trainer and physiotherapist Fabrizio Borra told the Spanish daily AS a week ago.

"He can continue for several more seasons if he wants to in perfect condition, because a driver at 35 in formula one today is at his physical peak," he added.
