Guardiola on Watford
"It (last May's FA Cup final) was the last game of the season; we played that game knowing we could be part of something unique in English football history.
"We had a few problems in the beginning but after that it was good. We won the Premier League a week before.
"Now it’s completely different. It’s the beginning of season, they have Quique Sanchez Flores. I saw the second half against Arsenal and, wow, it was incredible how they play.
"Every game has problems. I don’t compare with FA Cup game."
