Bilic took over from Sam Allardyce over the summer, and he has quickly altered the schedule and structure of training.
West Ham now are given Mondays off, but when they are on the practice field, a lot more precedence is put on the side keeping the ball.
“We only get one day off now,” Carroll said. “It’s a Monday and I’ve never had a Monday off before. It’s a lot different, now that we train for days before the game
“Even in training [we’re encouraged] to be calm on the ball, and carry on passing. That’s the main thing he's changed.”
Allardyce’s West Ham teams were generally built to be robust, but they were not designed to keep possession at all costs.
Bilic, on the other hand, has been keen to add to their creativity and style since taking charge, and the Hammers have benefitted from this ethos.
West Ham have appeared one of the Premier League’s most dangerous sides, and they have climbed into fifth place in the standings, as a result.
The Hammers’ next match comes after the international break against Tottenham Hotspur, where they could further strengthen their claim for a European spot with a victory.
