Danny Higginbotham has used social media to criticise the refereeing performance of Michael Oliver during the Manchester derby at the Etihad Stadium on Sunday afternoon.
United prevailing on opposition territory after Marcus Rashford scored a brilliant individual goal during the first half to move Louis van Gaal's men back into contention for a top-four position in the Premier League table.
However, the fixture involved a number of talking points and the general feeling is that Oliver made two wrong decisions at key moments in the game.
Just before half time, Rashford appeared to be felled by Martin Demichelis in the penalty area but Oliver waved play on, neither awarding the spot kick or brandishing a yellow card if he felt that there had been no contact.
Late in the game, Chris Smalling - who had already been booked - tripped Sergio Aguero, but despite awarding a free kick, Oliver did not caution the United defender for a second time.
After the second incident, Higgonbotham - who began his career at Old Trafford - had this to say about the referee.
Think the ref has just evened things out. Definite penalty not given for MUFC but second yellow not shown to Smalling— Danny Higginbotham (@Higginbotham05) March 20, 2016
United's win has taken them to within one point of City in the standings.
