On 1 May 1994, Ayrton Senna was killed during the . Prost was a pallbearer at his funeral. Speaking four years after Senna's death, Prost told Nigel Roebuck that he had "always refused to speak about him". Prost stated that when Senna died "a part of himself had died also", because their careers had been so bound together. Senna had also felt the same when Prost had retired at the end of 1993, when he admitted to a close friend that he had realised how much of his motivation had come from fighting with Prost. Only a couple of days before his death, when filming an in-car lap of Imola for French television channel TF1, he greeted Prost, by then a pundit on the channel: "A special hello to my...to our dear friend, Alain. We all miss you Alain." Prost said that he was amazed and very touched by the comment.
