New Leicester boss Brendan Rodgers has warned his squad they will suffer in their quest for success.
The 46-year-old has signed a contract until 2022 at the King Power Stadium.
He watched Tuesday's 2-1 win over Brighton, Leicester's first victory since New Year's Day, after being announced as the replacement for the sacked Claude Puel just hours before.
Rodgers will take charge for the first time in Sunday's trip to former club Watford.
He told the club's official website: "We'll work very hard on the training field. That's what you have to suffer as a player - you've got to work hard, so that when you come into the games, it becomes automated work.
"Hopefully we can bring in a structure to how we play, which firstly means that you've got to defend well, so you've got to press the game.
"Supporters maybe have seen my teams at Swansea and at Liverpool and at Celtic and will recognise how intensely we try to press the game.
"That's the base then to use your qualities technically so that will be something that we look to do over the course of time."
