Manchester United manager Jose Mourinho has launched an investigation to find out which of his players has been leaking team information before games.
According to the Sun, a United fan has been receiving the Red Devils' starting lineups before matches, which have sometimes been revealed the night before Premier League games.
The Sun were reportedlyshown the starting lineup before United'sEuropa League showdown with Ukrainian sideZorya Luhansk. The leaked team information correctly predicted 10 of the 11 starting players.
A source told the Sun Mourinho was fuming with the mole and desperate to conduct a witch-hunt to find the responsible party.
Mourinho is spitting feathers after Âdiscovering he's being betrayed by someone within the club," the source revealed.
This sort of information is gold dust for opposition managers and gamblers.�
Teams have been revealed prior to every United match so far this season, andMourinho endured the same problem at Chelsea last season, accusing his squad of "betrayal" before he was eventually sacked following his side's poor start to the season.
Mourinho visits Stamford Bridge for the first time as United manager on Sunday afternoon to take on Antonio Conte's Chelsea.
