Mayo manager James Horan was left to rue what he concluded were "too many basic mistakes" in their Allianz FL Division 1 defeat to Tyrone in Omagh.
The westerners went down on 2-15 to 0-16 scoreline and are pointless after two games.
Horan's comment came in the immediate aftermath of the match and while his tone did not convey a need to starting pushing the alarm bells, there was no denying his sense of frustration as he felt his side were part-architects of their own downfall.
Speaking to RTÉ Sport he said: "We did a lot of good things in the game, but we also left ourselves open on too many occasions.
"When we had momentum we were pulled up twice for picking the ball up off the ground and were also penalised for over-carrying. We coughed up easy possession.
"All those things add up and it gave Tyrone back the momentum when we were doing well. They got a few scores and it was hard for us to come back."
Horan will also reflect on the goal opportunities missed – with David Drake and Aidan O’Shea spurning some gilt-edged chances.
"We had periods of dominance in the game and we didn’t get the return from that. That can demoralise a team and be just the fillip for the opposition.
"In many respects we aided [Tyrone's] cause today. Overall we need to smarten up and smarten up quickly. But we will."
