Tottenham chairman Daniel Levy has accepted responsibility for Sunday's chastening 6-1 defeat against Newcastle after confirming that acting head coach Cristian Stellini has been relieved of his duties. Stellini had been placed in charge on an interim basis after former head coach Antonio Conte agreed to leave the club by mutual consent last month. But Stellini has now paid the price for Tottenham's humiliating defeat at St James' Park, where they made the worst possible start after conceding five times in just 21 minutes. Ryan Mason will step in to take charge "with immediate effect" while the club continue with their process to find a new head coach. Levy has attracted widespread criticism from fans and pundits alike this season in the wake of a disappointing campaign. And in the statement which confirmed Stellini's departure on the club's official website, the Spurs chief shouldered some of the responsibility for Sunday's horrific result. The statement read: “Dear all, Sunday’s performance against Newcastle was wholly unacceptable. It was devastating to see. We can look at many reasons why it happened and whilst I, the Board, the coaches and players must all take collective responsibility, ultimately the responsibility is mine. Commenting on this unusual way of announcing the expulsion of the interim coach, one of the tweeters wrote: "Daniel has become like an uncle." Another tweeted: "Looks like Levi dropped his second name to make it more elegant and become Uncle Daniel." While another tweeted sarcastically: "Who is Daniel? That's nice."
