Howard Webb has been named as the man in the middle for Sunday's Premier League showdown between Manchester United and Chelsea at Old Trafford.
The Red Devils will be replaced by the Blues at the top of the table on goal difference with just two games of the season remaining should the visitors triumph.
Sir Alex Ferguson claimed in the wake of United's 1-0 defeat by Arsenal at Emirates Stadium on Sunday that key decisions have gone against his side this term.
Ferguson felt United should have been awarded a late penalty when Michael Owen went down under Gael Clichy's challenge, although he accepted Nemanja Vidic was fortunate to escape handling in the area in the first half.
The Scot was hit with a five-game touchline ban after criticising Martin Atkinson following his performance during the first meeting between the two sides at Stamford Bridge in March.
However, World Cup final referee Webb came down on United's side when he gave them a penalty against Liverpool in an FA Cup tie earlier this season.
That led to former Reds forward Ryan Babel posting a mocked-up picture of the Yorkshireman wearing a United shirt on Twitter, earning the Dutchman a £10,000 fine.
