The user took to social media to share a clip showing why he was so angry, and his post has attracted more than 11,000 likes.
The eight-second clip shows the gamer’s goalkeeper, a ficitonalised version of Notts County shot-stopper Aidan Stone, with the ball in his hands.
But instead of finding a team-mate with a pass Stone bizarrely throws the ball into his own net, gifting the opposition a late equaliser.
The gamer fumed on social media before later revealing the keeper redeemed himself by saving two penalties in a Europa League quarter-final tie.
Stone went on to save a penalty in the Europa League final but that did not prevent the gamer and other Twitter users slamming the Football Manager.
He wrote: “I’m very close to destroying my computer.”
A follower responded saying: “Matchfixing investigations required 😂”
Another added: “Match fixing.”
A third wrote: “My iMac would be broken.”
