The appointment of referee David Coote for Manchester United's trip to Aston Villa this weekend has not gone down well with Villa supporters who still remember his last United game in charge.
United edged past West Brom 1-0 in November 2020 after Coote controversially went to VAR to reverse a decision to award a penalty against Bruno Fernandes.
A fake Facebook bio featuring Coote on the pitch at Old Trafford has had rival fans pointing towards a United conspiracy involving the Professional Game Match Officials Limited who appoint referees to games.
However, with officials having to fill in a form ahead of the season including the team they support and where they live, accusations of bias are easily avoided.
Not all Premier League referees' allegiances are known, but some are a lot more open than others as Planet Sport finds out.
Martin Atkinson - Leeds United
Born in Bradford and based in Leeds, Atkinson is a Leeds United supporter.
It has not stopped him taking charge of games involving bitter rivals Manchester United, however, with Atkinson regularly criticised by United fans for seemingly favouring their opposition. Their history with Atkinson actually dates back to 2003 when as a linesman he allowed a Thierry Henry goal to stand even though the striker appeared yards offside.
Most likely to be seen refereeing Liverpool: Atkinson has taken charge of 69 Liverpool matches.
Stuart Attwell - Luton Town
Attwell hails from Nuneaton but is a Luton Town fan. Understandably, he has never officiated a Luton game but did make headlines in 2008 when he awarded a goal for Reading against their bitter rivals Watford despite the ball crossing the line outside the back post.
Peter Bankes - unknown
It is not known who Lancashire-born Bankes supports. He began refereeing aged 14 in 1996 and is a coach and mentor within the Liverpool County Football Association. He has never officiated a match involving Liverpool, Everton or Tranmere.

Most likely to be seen refereeing Grimsby Town: Brooks is only 249 games into his career but has refereed the Mariners 11 times.
David Coote - unknown
Despite a fake Facebook bio appearing to state otherwise, it is not known who Nottinghamshire-based Coote supports. He has never officiated a game involving Nottingham Forest or Notts County, however.
Most likely to be seen refereeing Sheffield United or Wolves: Coote has refereed both sides 19 times.
Mike Dean - Tranmere
Based in Heswall on the Wirral there can be little doubt about Dean's allegiances thanks to a much-shared video following Tranmere's play-off semi-final win over Forest Green in 2019. Dean has followed Rovers home and away since the mid-1980s.
Most likely to be seen refereeing Manchester United: The 53-year-old has taken charge of 82 United games, dishing out 21 penalties to the Red Devils.
Darren England - Barnsley
England, from Little Houghton, grew up supporting Barnsley and even worked for their Reds in the Community charity.
Promoted to the Select Group for 2021/22, his elevation came 16 years after he took charge of his first match in the Barnsley Sunday League as an 18-year-old - sending someone off for a headbutt.
Most likely to be seen refereeing Derby County: England has refereed the Rams 13 times.
Kevin Friend - Leicester City
Born in Bristol but based in Leicester, Friend was controversially dropped from Tottenham's Premier League game at Stoke in April 2016 due to Spurs being in title race with the Foxes.
Most likely to be seen refereeing Liverpool: Friend has taken charge of 36 Liverpool games, one more than their cross-city rivals Everton.
Jarred Gillett - unknown
The Australian made history in September 2021 when he became the first non-British or Irish referee to take charge of a Premier League match. It is not known if the Gold Coast-born whistler supports a British side, however.
Most likely to be seen refereeing Blackburn Rovers: In his native Australia, Gillett has taken charge of 38 Melbourne Victory games. However, over here it is at Blackburn where he has been seen most regularly, taking charge of eight Rovers games.
Tony Harrington - Hartlepool
Grandson of Pools legend Tommy McGuigan, Harrington was one of the four referees promoted to the Select Group for the 2021/22 campaign.
Harrington began refereeing in the Teesside Junior Football Alliance at 14 having completed a basic refereeing course as part of the Duke of Edinburgh award.
Most likely to be seen refereeing Blackburn Rovers: Harrington has officiated in 21 games involving the Ewood Park side.
Simon Hooper - Swindon
A promising centre-forward, he was released by Swindon Town at the age of 16 after seven years at the club. Went on to play semi-professionally for Highworth Town and Swindon Supermarine.
Most likely to be seen refereeing Brighton: Hooper has been the man in the middle for 25 Brighton games, three more than nearest rival, Bournemouth.
Robert Jones - unknown
Merseyside-based Jones is in his second season in the top flight. He has never taken charge of a first-team match involving Liverpool, Everton or Tranmere. However, he has refereed matches involving both Liverpool and Everton's under-23 sides.
Most likely to be seen refereeing Leeds United: Jones has overseen 12 games involving the Elland Road side.
Chris Kavanagh - unknown
Another referee for whom there is huge conjecture as to who he supports, with the whistler having been born in Manchester.
The fact that he has taken charge of eight United and seven City games means that despite the speculation, he does not follow one of the big teams. Suggestions that he supports Stalybridge Celtic have not been confirmed.
Most likely to be seen refereeing Leicester City: Kavanagh has taken charge of 20 Leicester matches, with the Foxes losing 11 of them.
Andy Madley - unknown

Andre Marriner - Aston Villa
Andre Marriner hails from Birmingham and admits he is a fan of Aston Villa. "I go as much as I can and my two kids are season ticket holders."
It means he hasn't taken charge of games involving Villa or Birmingham, though he has refereed two West Brom matches.
Most likely to be seen refereeing Manchester City: Marriner has been in charge of 59 City games, two more than next highest, Liverpool.
Jon Moss - Sunderland
Born in Sunderland, Moss is now based in Horsforth, Leeds. Played at academy level, firstly for his hometown club Sunderland and then for Millwall and went on to become a PE teacher in Leeds, where one of his pupils was James Milner. He later sent Milner off in a Premier League match in 2019.

He is not allowed to referee Newcastle or Sunderland games and will not be allowed to take charge of any games towards the end of the campaign involving any of the Magpies' relegation rivals.
Most likely to be seen refereeing Liverpool: With Liverpool are Newcastle fighting it out at opposite ends of the Premier League table, Oliver has been able to take charge of 49 games involving the Reds.

Salisbury, from Penwortham, started refereeing in the local leagues in Preston in 2001 after being inspired by his dad Graham, who has just retired after 588 Football League games.
The former PE teacher's soccer allegiances are not known but his Preston base means he has never taken charge of a game involving the Lilywhites.
Most likely to be seen refereeing Coventry City: Salisbury has taken charge of 13 Sky Blues games and they have yet to lose with him in the middle.
Graham Scott - Swindon
A former goalkeeper with Abingdon Town, Scott was promoted to the Select Group in 2015.
Living in Oxford, Scott is unable to referee the Robins or the U's.
Most likely to be seen refereeing Brighton: Scott has taken charge of 22 matches involving the Seagulls, with Southampton next best on 21.
Anthony Taylor - Altrincham
Taylor lives just six miles from Old Trafford and his appointments for games involving Manchester United often draws the ire of rival supporters.
However, the 43-year-old from Wythenshawe is as neutral as they come, being a fan of non-league Altrincham.
Most likely to be seen refereeing Liverpool: Taylor has taken charge of 47 games involving the Reds, with Liverpool losing just nine of them. For comparison's sake, in 38 games in charge of Manchester United, the Red Devils have lost 10.
