The Gunners put on a poor performance, as Wenger’s wait for a League Cup success went on, while Pep Guardiola lifted his maiden silverware in England.
With the already under-fire Arsenal boss overseeing his men outdone on the Wembley turf, salt was rubbed in the wound by the fourth official during the final stages of proceedings.
Goals from Sergio Aguero, Vincent Kompany and David Silva handed Wenger a painful loss at Wembley, but what the fourth official told him would have been just as hurtful during injury time.
French boss Wenger was humorously trolled by touchline official Graham Scott when he questioned the amount of added time that was allocated.
The long-standing Gunners coach shed light on the exchange during his post-match press conference.
Wenger to fourth Official: “Why don’t you allocate the correct amount of injury time.”

Arsene Wenger "When I asked the fourth official why he didn't give more stoppage time, he replied by saying 'why do you want more time?'"
The official was clearly looking to aid Wenger by putting his side out of their League Cup final misery, as the Sky Blues recorded a comfortable 3-0 success.
