Chelsea boss Antonio Conte admits his touchline behaviour could be bad for his health.
He keeps to strict fitness and dietary regimes which means sometimes missing out on treats like homemade spaghetti and Nutella.
"I am worried about this," said Conte. "I know there's a bit of a risk.
"For this reason I try to run and maintain a good physical form, and I might put on a GPS monitor to control my heart."
