LONDON (REUTERS) - Leicester City face the latest challenge of Claudio Ranieri's remarkable managerial reign on Saturday (Sept 17), to come back down to earth from the high of a Champions League win for a domestic game against Burnley.

Ranieri, who led City to a stunning Premier League title triumph in his first season in charge last term, will not accept any excuses.

"For us everything is new, I want to see how my players respond," the Italian told a news conference on Friday.

"They told me they are okay and they must show this on the pitch. We don't have excuses because if they beat us, they are better than us."

Leicester won 3-0 at Club Bruges in their first-ever Champions League match in midweek.

"I'm so pleased with our performance," Ranieri said.

The champions have won only one of their opening four Premier League games.
