Arsenal's talisman Pierre-Emerick Aubameyang worked his Wembley magic once again as they came from behind to beat Chelsea and win the FA Cup for a record 14th time.
Chelsea took the lead in the Heads Up FA Cup final inside five minutes through Christian Pulisic's smart finish but then fell victim to the brilliance of Aubameyang, who was also Arsenal's hero when he scored twice in the semi-final win over Manchester City.
The Gabon forward drew Arsenal level from the penalty spot before the break after he was fouled by Chelsea captain Cesar Azpilicueta, then produced a moment of world-class finishing to make the defining contribution to the first behind-closed-doors FA Cup final.
Chelsea were hampered by a first-half injury to Azpilicueta and were struggling even further when they lost the outstanding Pulisic to a hamstring problem after the break.
As the Blues battled to overcome those setbacks, the brilliant Aubameyang was able to give Mikel Arteta silverware in his first season as the Gunners' manager.
Aubameyang, who Arsenal are understandably desperate to secure on a new long-term contract, turned Chelsea defender Kurt Zouma inside out in the 67th minute before delivering the most audacious finish, chipping over keeper Willy Caballero from an angle.
Chelsea's agony increased further when Mateo Kovacic was very harshly sent off for a second yellow card, awarded by referee Anthony Taylor for the most innocuous of challenges on Granit Xhaka.
Arsenal closed out the win to secure a place in the Europa League next season but it was bitter disappointment for Chelsea manager Frank Lampard at the conclusion of his first campaign in charge.
