Manchester United had a big security breach ahead of their game against Aston Villa as their dressing room was reportedly bugged.
The Red Devils and Villa played to a goalless draw at Villa Park seven days ago, which saw Erik ten Hag's men extend their winless run to five matches across all competitions.

The Sun have reported that a prankster planted a hidden device in the away dressing room two days before the Premier League encounter.
It is believed the device record Ten Hag's team-talk to his players, although the Sun have reported that they will not release the audio.
The Sun also revealed that the prankster was a Red Devils supporter, who used a dodgy Chinese phone that sticky-taped out of view any of the players.
"This is a shocking breach of security and some serious questions will be asked as to how this was allowed to happen. Fortunately, there was nothing sinister to this incident," a source told the Sun.
"It was just a prankster, who's actually a United fan, being silly and wanting to hear what was said inside those four walls. But it will definitely be a cause for concern about how they managed to get inside a changing room at one of the Premier League's biggest clubs just days before a match."
