David Humphreys, does not believe he has cemented his place in the side for Saturday's match against Italy in Rome, despite a 26-point display in Edinburgh yesterday.
Ireland's record Six Nations points-scorer was recalled to the fly-half role when Ronan O'Gara withdrew through injury last week and he turned back the clock in sensational fashion, scoring all but 10 of his side's points in a 36-6 romp.
Coach Eddie O'Sullivan, who plans to name his team on Wednesday, could be facing a selection dilemma if his first-choice number 10 has, as expected, recovered from the ankle injury he sustained in the Celtic League final.
"We've a great luxury at the moment to have two great fly-halves in Ronan O'Gara and David Humphreys," said O'Sullivan.
The form of the 31-year-old Humphreys, who ran the show at Murrayfield in addition to scoring a try and eight goals, ought to ensure he starts in Rome regardless of the fitness of O'Gara but he's not so sure.
"I honestly haven't considered that," he said. "He's been the man in possession, he's been playing well. I'm just delighted that I've put in a performance that's compared to some of his."
The 25-year-old O'Gara, who has played a prominent role in Munster's successful season so far, has gradually nudged ahead of his rival and made a huge contribution to Ireland's victories over Australia and Argentina in the autumn internationals, kicking 10 out of 10 goals in those two games to take his points tally to 273 in just 27 games.
But Humphreys, who took over from the great Jackie Kyle as Ireland's most capped outside-half when he won his 48th cap at Murrayfield, showed he can still perform at the highest level by producing a consummate display against the Scots.
His 26-point haul, which included eight goals from nine attempts, took him to within four of O'Gara's Irish match record, set against Italy three years ago.
"Thankfully a few went over," he said. "But the game was won by the pack, it always is at this level. The front five were outstanding and it made it easy for the backs.
"I was just delighted that we won, that was the main thing. We were under a lot of pressure going into the game because we hadn't won there for a while.
"It was my third start there and the first time I've won, so it's been a long time coming."
