Old Trafford witnessed a Premier League shocker on Monday as 10-man Everton stunned Manchester United with a 1-0 victory, a result that compounded the pressure on United's manager, Ruben Amorim. The Toffees secured their first win at Old Trafford in 12 years, thanks to a moment of brilliance from Kiernan Dewsbury-Hall, but the game will be remembered for Idrissa Gueye's early red card after an altercation with his own teammate, Michael Keane.

The incident occurred just 13 minutes into the match. Following a missed scoring chance by Bruno Fernandes, Gueye and Keane exchanged words, which quickly escalated. In a moment of madness, Gueye slapped Keane in the face, leaving referee Tony Harrington with no choice but to issue a straight red card. The Premier League Match Centre confirmed the dismissal was for "a clear strike to the face of Keane," a decision checked and upheld by VAR.

Despite being a man down for over 75 minutes, Everton, managed by David Moyes, displayed remarkable resilience and tactical discipline. In the 29th minute, Kiernan Dewsbury-Hall surged forward, skillfully evading challenges from Bruno Fernandes and Leny Yoro before unleashing a stunning strike into the top corner of the net. The goal sent shockwaves through Old Trafford and ignited the Evertonians in the away end.

Amorim, marking the first anniversary of his tenure at Manchester United, attempted to change the game's momentum by introducing Mason Mount for Noussair Mazraoui at halftime. However, United struggled to break down Everton's stubborn defense, failing to capitalize on their numerical advantage. Frustration grew among the home crowd as Everton maintained their lead, with goalkeeper Jordan Pickford making crucial saves to deny United's late attempts to equalize.

The defeat marks a significant setback for Manchester United and Amorim, especially as it was their first loss after an unbeaten run of five games. United's disjointed performance and lack of creativity in the final third raised further questions about their ability to compete for a Champions League spot.

Everton's victory, on the other hand, is a testament to their fighting spirit and tactical organization under David Moyes. Overcoming the early setback of Gueye's dismissal, they defended resolutely and seized their opportunity to secure a vital three points. This win propels Everton to 11th place in the Premier League standings, level on 18 points with Manchester United, who slip to 10th.

The sending off of Gueye will result in a three-match ban for violent conduct, as well as a potential fine from both the club and the Premier League. After the match, Gueye reportedly apologized to Keane and his Everton teammates for his actions.

The result leaves Amorim with much to ponder as his team selection included six players who also started his first match a year ago: Bruno Fernandes, Noussair Mazraoui, Amad Diallo, Diogo Dalot, Matthijs de Ligt, and Casemiro. Despite this familiarity, United looked a shadow of the team Amorim is trying to build, struggling to break down a determined, albeit shorthanded, Everton side.
