Watch: Con O'Callaghan Gives Dublin The Perfect Start With A Goal Inside 90 Seconds

It took less than 90 seconds for Mayo to get that sense once more of deja vu.

So often has the Connacht side started All-Ireland finals poorly, and it happened again on Sunday afternoon, with Con O'Callaghan sauntering through the Mayo defence to score an early goal.

Like he did against Tyrone in the semi-final, the Cuala star sent Hill 16 in delirium with the early goal. Somehow he was able to get though Colm Boyle and Keith Higgins, before rolling the ball past David Clarke in the goals.

Since the early goal, Mayo have found their way into the game, despite the disastrous start. They scored the following three points to equalise. Dublin lead 1-01 to 0-03 after 15 minutes.
