Fernando Alonso has rejected McLaren’s verdict on the pre-season crash that left him concussed and said it was caused by a steering problem. The Spaniard has been passed fit to return to action at this weekend’s Malaysian Grand Prix, where he spoke about the accident for the first time. Although the team said there was no sign of a failure, Alonso said the car “definitely had a steering problem”. He also denied he had come round after the crash thinking he was 15.
