Yahoo Sports reports: Pep Guardiola threatened to quit Manchester City "100 times" during his decade-long reign as manager but chairman Khaldoon Al Mubarak said this time he knew the Spaniard "actually meant it". Guardiola, 55, stepped down at the end of this season after leading the club to 17 major trophies, including six Premier League titles and a Champions League victory. Before last month's FA Cup final victory over Chelsea, Guardiola was asked whether the visit to Wembley Stadium would be his last.
