JAKARTA — If Claudio Ranieri was in front of a television when English Premier League soccer champions Leicester City hosted five-times European club champions Liverpool on Feb. 27, the mild-mannered Italian might have been tempted into an uncharacteristic show of anger. The 65-year-old had been sacked as team manager three days previously by Leicester City’s billionaire Thai owner and chairman Vichai Srivaddhanaprabha, founder of the King Power Group chain of duty-free shops. After a series of tepid losses, the team had been dragged into a struggle with a half dozen rivals desperate to stave off relegation from the premier league to the less high-profile English Championship, where Leicester City had languished for a decade prior to 2014. But with Ranieri gone, the team rediscovered the verve that brought them success the previous year. Ranieri’s ex-charges followed their comfortable 3-1 win over Liverpool with a March 4 victory over Hull City by the same margin.
