However, while many have already written off Ireland's chances of springing what would now be a major surprise, Doyle insists there is no cause for despondency.
He said: "We are probably more confident. In the chances in the game, we probably had the best going.
"Their goal was slightly on the fortunate side, I reckon, and we had two or three nearly clear-cut chances which we could have scored from.
"It will be easy to lift ourselves. It's the reason you play football, games like this.
"It's 90 minutes, or maybe more, to get to a World Cup."
That said, Giovanni Trapattoni's men know they face an uphill struggle at the Stade de France after Nicolas Anelka's deflected strike left France in pole position to claim a berth at next summer's finals in South Africa.
While the Republic matched their more illustrious opponents before the break in Dublin, they were eventually ground down and could not really complain about the outcome, even if there was a touch of good fortune about Anelka's winner.
Doyle said: "They were very good. They had lots of possession - we knew that was going to be the way, that they would have lots of possession, but we limited them to not creating too many chances.
"They are a similar team to Italy, maybe more attacking than Italy and they maybe leave a bit more space for us to attack because of that.
"But you see their bench, you see the subs they can bring on. It's amazing the players they can bring into the team, and we are going to have to be very wary of that on Wednesday."
Ireland will need no added motivation going into the game, but if they did, it was provided by Real Madrid midfielder Lassana Diarra on the final whistle on Saturday.
His suggestion to Keith Andrews that the tie was over sparked an angry melee, and that will not be forgotten when hostilities resume in Paris.
Doyle said: "A few of the lads were upset by one or two comments at the end of the game, but that will only help us on Wednesday."
