(FILES) In this file picture taken on April 19, 2014 Southampton's Argentinian manager Mauricio Pochettino arrives for the English Premier League football match between Aston Villa and Southampton at Villa Park in Birmingham.  Tottenham appointed Mauricio Pochettino as their new manager on a five-year contract on May 27, 2014. Pochettino was tipped to take charge at White Hart Lane following the recent sacking of Tim Sherwood and the Premier League club confirmed they have persuaded the former Argentina defender, who had earned widespread praise during his time as Southampton boss, to quit his post at St Mary's and move to north London.
