West Ham boss Slaven Bilic warned his side will be punished if it switches off on set pieces against Leicester City.
Slaven Bilic knows "on fire" Leicester City are capable of bringing West Ham back down to earth in his first Premier League home game in charge of the London club.
Bilic could scarcely have hoped for a better start in the top flight as he masterminded a 2-0 derby victory over Arsenal at the Emirates Stadium last Sunday.
West Ham had not beaten Arsene Wenger's side for eight years, but goals from Cheikhou Kouyate and Mauro Zarate ended that dismal record on the opening weekend of the season.
