The Foxes returned to training on Monday, and will head for a training camp in Austria later this month.
The manager told the club's website: "Two things you look for when the players come back into training is their physical and mental shape. They look in really good condition and I've been really pleased with their application.
"It's a short-ish pre-season this year, but I feel like we're already a week ahead of where we were last year, which bodes well for the coming season. Last year was a pretty low experience, but you've got to be able to manage that and bounce back pretty quickly and I think we will manage that.
"This group of players did very well last year and I would expect them to do well again in the coming season and improve on that. It's a time of year where there is speculation about your own players and players from elsewhere and I'm not going to get involved in that."
Leicester reached the Championship playoffs last season, but lost to Watford in the semi-finals.
