Juventus fullback Patrice Evra admits playing in Serie A has taken a big adjustment.

Evra left Manchester United last summer for Juve.

"In football you never stop learning. I knew a bit about Juve and its history, but it was a shock for me. I heard Zinedine Zidane say he threw up after the first training session, but I thought it was a legend. It wasn't.

"Coach Max Allegri asked every day how I was and I'd reply: 'For the moment I am still alive.' I have never trained so hard in my entire life.

"I heard many people say Serie A is easy. You might think that when you're outside, but now I'm there, it's absolutely not true.

"The difference is that in England football is like two boxers and the first to get tired loses the match. In Italy the tactics are fundamental and I remember even at 17 thinking all the Italian teams were so well-prepared.

"An English player can come to Italy and do badly, just as an Italian can, but you have to be intelligent enough to realise they are different Leagues."
