The Croat was surprised at the intensity of the Premier League.
Speaking to the club's official website, West Ham United boss Slaven Bilic has revealed that he and his coaching staff regularly spoke about the intensity of English football throughout the 2015-16 Premier League season.
The Irons finished seventh this past season but it could, and probably should, have been higher, though Bilic's side stuttered somewhat in the final stretch when Champions League qualification looked on the cards
In the end, they did not even finish in the Europa League spots, but the Hammers may still qualify for Europe's secondary competition if Manchester United beat Crystal Palace in Saturday's FA Cup final at Wembley.
In any case, Bilic, so far, has been proven a success in East London after replacing Sam Allardyce last summer, but the Croat, who played for West Ham and Everton during his three-year stint in England as a player, had the advantage of knowing what to expect.
England's top flight is famed for its intensity, and the 47-year-old admits he and his staff spoke about this quite often this past season.
"The intensity of this league is always a surprise when you arrive. You are not playing all the time but it feels like that. Even that is not negative though," he told the club's official website.
"My staff and I spoke about this a lot during the season. We enjoyed it very much."
