Jose Mourinho has reportedly begun searching for the source of a leak within his Tottenham Hotspur squad following recent complaints over his training methods.
The Athletic reported last month that a number of Spurs' players had grown "bored and frustrated" of Mourinho's training drills.
Tottenham's season has gone from bad to worse since then, having been knocked out of the Europa League with a shock defeat to Dinamo Zagreb last week.
According to the Daily Mail, Mourinho is annoyed that members of his dressing room are talking to the press behind his back and has vowed to seek out the mole.
The incident echoes the final weeks of his first Chelsea tenure when Mourinho called out the "rats" in his squad after stories were leaked to the media.
