Finn Russell believes the real Scotland are ready to emerge from the wreckage of their injury-hit Six Nations and take the World Cup by storm.
Having had to do without a number of key players earlier in the year, Gregor Townsend's squad are almost back at full strength ahead of Pool A opener against Ireland.
Back-rower Jamie Ritchie will not be risked as he steps up his recovery from a broken cheekbone while Exeter flanker Sam Skinner was the only casualty to be ruled out before the tournament.
Ireland boss Joe Schmidt, on the other hand, has fitness concerns over centre Robbie Henshaw and full-back Rob Kearney.
Now fly-half Russell reckons his side are primed to show their true capabilities.
"We're excited going into the World Cup," the Racing 92 man told the PA news agency.
"The Six Nations was up and down - it all seemed to be games of two halves. Against Italy the first half was great, then we let in three late tries. We had a good first period against Ireland too but slipped off again. Then the England game was like that but in reverse.
"What was frustrating was that we never really managed to put in an 80-minute performance. In a World Cup against the best teams on the planet you have to put in a 80-minute display every game.
"But it should be the real Scotland we see now. This is the main stage, the World Cup, so if it's not the real Scotland we see then it will be disappointing for all of us.
"On our day, if we get things right we're definitely capable of getting out of the group. From there it's knock-out rugby and you take it game by game.
"We're here to do our job and give our best performance. If we stay injury-free I think we're in a great position to do that."
Sunday's clash at the International Stadium could come down to a battle of wills between Russell and Irish superstar Johnny Sexton.
The British and Irish Lions fly-half has endured a difficult 2019 but Russell dismissed suggestions his rival's powers are on the wane.
He said: "Johnny's a classy player. He was World Player of the Year last year so he's still up there with the best.
"He always leads Ireland really well. He's had quite a few injuries lately but his influence is definitely still as strong.
"I don't know what goes on in their camp but the feeling I get from the outside is that he is as respected as the coaches in what he has to say."
