Man City's O'Reilly savours 'unbelievable' double in League Cup final win
O'Reilly turned 21 on Saturday and followed his birthday celebration with a man of the match performance at Wembley.
The left-back punished a mistake from Arsenal goalkeeper Kepa Arrizabalaga to open the scoring with a close-range header on the hour.
And O'Reilly struck again with another header four minutes later to give City their ninth League Cup triumph.
"Unbelievable feeling. To win a final, to beat this team we know how good they are. We need to build on it, it will give us good momentum.
