Real Madrid boss Carlo Ancelotti has sensationally revealed how he "tried to kill" a Chelsea player during his time in charge in west London, reports the Daily Mail.
The Italian tactician refused to name and shame the individual involved, before adding that the key to successful management is mutual respect between players and coaches.
Ancelotti won the Premier League and FA Cup double in 2009/10 during his stint at Stamford Bridge, and for that reason will go down as one of Chelsea's most successful managers.
His handling of a number of high-profile Blues stars played an integral part in his achievements in England, though the 54-year-old admits in an interview with The Times that at one point he'd had enough of one player.
"We've never had any problems with the players, just one time at Chelsea," he explained. "One player didn't show respect and I tried to kill him but it wasn't possible.
"The player is the property of the club and sometimes you cannot do what you want."
The Chelsea star was understood to have had "a well-documented history of misdemeanours", which doesn't exactly narrow the search down, given the Blues squad's array of misconducts.
Ancelotti wasn't a manager to stand for players stepping out of line, and also recalled how he left former talisman Didier Drogba out of one Chelsea squad after the striker turned up late for a game.
"One time Drogba arrived 30 minutes late for a game, so he didn't play, but the key is mutual respect," he added.
