Ross Brawn has revealed he had to miss the Spanish Grand Prix because of an irregular heart beat. But the Mercedes team boss says he is back to full fitness after the scare.
"I had an arrhythmia, which is an irregular heart beat," Brawn told reporters in Monte Carlo ahead of the Monaco Grand Prix. "So I had to find out what had caused it, and when they understood what caused it they became a lot less worried – and certainly I became a lot less worried."
Brawn said he was fine now and that he had no long-lasting worries.
When asked what had caused the arrhythmia, he joked: "I think it was Manchester United [soccer team] that did it."
