(Reuters) - Manchester City’s official supporters club has told manager Pep Guardiola to stick to coaching after he commented on the thousands of empty seats for their Champions League win over RB Leipzig at the Etihad Stadium on Wednesday. Kevin Parker, the general secretary of City’s official supporters’ club, told British media he was surprised by Guardiola’s comments. “Of course he would want a full house but I don’t know why he would question whether we’d have one against Southampton,” Parker added. “We have played two Saturday home games and the stadium – from a City perspective at least – was full on both occasions. I don’t think anybody anywhere within the club should be questioning the loyalty of the supporters.
