Guardiola holds his head in frustration due to Donnarumma's serious mistake.

Manchester City loses the lead advantage against Arsenal in the "final" match between both teams at Etihad after goalkeeper Donnarumma's error.

Hosting Arsenal at their home ground Etihad, Manchester City quickly gained an advantage with the opening goal. In the 16th minute, Cherki rushed forward to seize the ball after a block by an Arsenal defender; the French player dashed into the penalty area, bypassed Gabriel's pursuit, and shot diagonally into the corner to score for Manchester City.

Although they quickly gained an advantage, Manchester City lost it just as fast due to goalkeeper Donnarumma's serious mistake.

Receiving a throw-in from his teammate, Donnarumma handled it slowly while Kai Havertz rushed in quickly. The Manchester City goalkeeper's clearance hit Havertz's foot, causing the ball to deflect into Manchester City's net, allowing Arsenal to equalize the score 1-1.

Witnessing his player's grave error, Guardiola couldn't believe his eyes. The Manchester City manager held his head in regret as his team lost the lead advantage in an unbelievable and unacceptable manner.
