Fans believe Bruno Fernandes missed his penalty on purpose during Manchester United's 1-0 loss to Aston Villa at Old Trafford on Saturday.
Fernandes skied his late penalty, resulting in United's first Premier League defeat of the season, and their third in four games.
The Portugal international has scored 22 of his last 23 penalties, and United fans on social media believe he missed on purpose in order to get manager, Ole Gunnar Solskjaer sacked.
The video begins with a message of: "This miss was not an accident."
Fernandes' penalty is shown and Cristiano Ronaldo is seen giving his teammate encouragement. Following that clip, an incident involving Steven Gerrard and Roy Hodgson is seen.
Hodgson left Liverpool in 2011 after a 3-1 loss to Blackburn Rovers - a game in which Gerrard missed a penalty, and fans were convinced he missed it on purpose.
United were knocked out of the Carabao Cup by West Ham last Wednesday, and speaking after the game, Solskjaer said: "Early kick-offs... It's hard when you play Wednesday night. That's part of the reason we did what we did on Wednesday night."
Fernandes took to social media to apologise for his miss, and wrote: "Nobody is more frustrated and disappointed than me for missing the penalty and the consequent defeat. I've always assumed my responsibilities and I've always embraced them under pressure in moments like this.
"Today, I failed. Criticism and contrasting opinions are a big part of football. I've learned to live with it, even using them to drive me on, and I consider it all a very important part of my commitment to never stop trying to become the best player I can possibly be, for me and the team.
"Today I once again took the responsibility given to me almost since I joined United and I will take it again without any fear or dread whenever called upon."
