Nigel Pearson has identified one of the crucial differences for Leicester City following their promotion to the Premier League.
The Foxes won the Championship last season and have acclimatised to life well in the top-flight, but Pearson acknowledges that there have been noticeable contrasts in the game since stepping up a level.
The Leicester boss believes that his side now have to show greater concentration due to the rise in the intensity of games and the amount of time the ball is actually in play for.
“There are a lot more high intensity movements so you’ve got to factor in the mental side of the game,” Pearson said to the club's official site. “It’s even more important.
“A number of the games we’ve played so far, we’ve not had a lot of the ball compared to last year.
“That means you’re having to work exceptionally hard when you don’t have it.
“We do like to press from time to time but also the concentration levels have to be maintained for longer periods because you come up against a lot of sides who keep the ball very well.
“In a Championship game I would say that probably out of the 90 minutes the ball would probably be in play for about 55 minutes.
“I would think in the Premier League you could add another 10 minutes on to that.
“That in itself would suggest that there’s a lot more concentrating to be done through passages of play rather than when the ball goes out of play.
“You get a lot more of that in the Football League.”
Despite the difference in football standard, his side seem to have risen to the challenge.
Few teams have been impressive as Leicester immediately after reaching the Premier League and the club occupy a respectable position in the table despite a tough start.
They are unbeaten in front of their home fans, with draws against Everton and Arsenal being backed up with a win against Manchester United, while a victory over Stoke City on their travels confirmed their credentials.
It has given the club great belief that they will be able to avoid the drop this season and they will be hoping to continue their fine form as the season progresses.
Leicester's next match is against Burnley this weekend and they will be looking to get back to winning ways after losing to Crystal Palace last Saturday.
