Cillian O'Connor is likely to take over as the top scorer in senior football championship history when Mayo face Kerry in their All-Ireland quarter-final at Fitzgerald Stadium on Sunday.

O’Connor has scored 23-279 for his county in championship to date according to official Mayo GAA statistics, which leaves him just four points behind the current all-time top scorer, the Kingdom’s Colm Cooper, who racked up 23 goals and 283 points in his long career.

The fact that the Ballintubber man scores at a rate of seven points per game means there is a great chance that he will make history if, as expected, he starts in Killarney this weekend.

Certainly, if he stays fit for all three Super 8s games over the coming four weeks there seems little chance that he won’t take over at the top in 2019.

Cooper compiled his total across 84 games up to the age of 33 and took the crown from fellow Kerry legend Mikey Sheehy, who finished his trophy-laden 49-game championship career with 29-205 and now stands third on the all-time list.

The fact that O’Connor is just 27 years old and has played only 51 summer games makes his achievements all the more remarkable.

His scoring rate of seven points per game dwarfs the averages of every other player in the top ten and only the great Matt Connor can live up to it, the Offaly hero's playing career having been cut short by a car accident on Christmas Day 1984 at the age of just 24.

On first analysis, O’Connor isn’t particularly quick for an inter-county forward and he is almost completely one sided, relying solely on his right boot to do the damage.

His free-taking is exemplary however and his conversion rate from the dead ball is one of the reasons why Mayo have been so competitive for so long.

He can also score from play, as he showed with his dramatic equaliser which sent the 2016 All-Ireland final against Dublin to a replay.

He made his debut in a Connacht quarter-final against London in 2011 as a teenager, Mayo manager James Horan’s first game in his first stint in charge, and he has been keeping umpires busy ever since.

O’Connor only made his first appearance of the season as a substitute in the win over Armagh, scoring two points, and added another six in the defeat of Galway in Limerick last Saturday.

In his 51 championship appearances to date he has only failed to score in one of them - when he was black carded early on in the 2016 Connacht clash against London. His highest single game total was 3-09 against Limerick in last year's qualifiers.
