Manchester United and Chelsea officials have been told to clean up their acts after a recent visit from health inspectors to all Premier League football grounds, an environmental report has revealed.
The information - which was obtained through Freedom of Information requests - detailed some surprising findings about clubs in England's top-flight, highlighting a number of hygiene nasties from up and down the country.
An inspection carried out at Manchester United's Old Trafford stadium discovered a broken tap and flaking pipework, as well as previous problems with the presence of rodents, with the report instructing the club to "continue to monitor and react to the mouse activity".
In response to the report, a Manchester United spokesperson said that they had a "robust pest control system" in place, and that if any incidents do occur, they take "immediate and appropriate action".
Chelsea, meanwhile, who are bankrolled by Russian billionaire Roman Abramovich, were criticised for almost serving 'cooked turkey saddles' that were out of date, to supporters attending games at Stamford Bridge.
Health chiefs also expressed concerns about the selling of stockpot and several frozen steak and mushroom pies that were not labelled correctly, and warned the European champions that this was in "serious contravention" of hygiene laws.
A follow-up inspection did find action had been taken though, and noted hygiene at the west London club had become "generally excellent".
By comparison, Arsenal scored top marks with inspectors the first time round, with no contraventions of legislation witnessed at the Emirates Stadium, while reigning Premier League champions Manchester City were also given maximum points at the Etihad Stadium, with the inspector writing there was "very good hygiene standards in place".
