"I am feeling perfect," he told Chelsea's official website. "I had the virus, which has cleared now. I fully feel good, I feel fit, so I am feeling back to myself so it is all good.
"I had it [the illness] three weeks ago now I think, on a Monday when I felt a bit hot and I was thinking, 'this is a bit unusual, why do I feel this hot?'
"The next day I was feeling back to normal. I thought it was just a minor temperature thing, but obviously it wasn't. I said to myself this wasn't actually that bad, the symptoms, and I said to myself, 'I feel good, I feel better.'
"Everything is happening so fast and I did not know this virus would be such a major thing and so big in the world and affect so many people.
"Everyone has to be careful and judge things how they go and hopefully the virus will go soon and everyone will be back to normal."
