Juventus defender Patrice Evra has revealed that the Serie A club discovered a food allergy of which he was unaware during more than seven years at Manchester United.
The 34-year-old also noted that, after being sent to hospital for further check-ups, he found out that he had a stomach ulcer which could have worsened during play.
Evra told BBC Sport: "When I came here they said I'm allergic to eggs and I ate them every day in Manchester. I was vomiting in training at first.
"I went to the hospital and they told me I had been playing with an ulcer and I was lucky it was not bleeding inside."
The France international, who left Old Trafford in the summer of 2014, has played 47 times for Juve.
