Jack Ross says Hibernian will travel "with belief" they can beat Rijeka after a 3-0 win over Ross County took them top of the Scottish Premiership.
Hibs joined Aberdeen and Hearts at the summit after goals from Martin Boyle, Kyle Magennis and Christian Doidge.
Ross' side are tied at 1-1 at the midway stage of their Europa Conference League third qualifying round tie, with the return leg in Croatian on Thursday.
"I don't think we can go in any better frame of mind," he said.
"We'll go there with belief we can go win it."
County were not absent as an attacking force but just could not keep up with Hibs at times and still await a first win, goal and shot on target in the league under Malky Mackay.
Two Boyle crosses had gone abegging by the time the winger took charge with a 30-yard shot that looped up over Ross Laidlaw off Coll Donaldson's desperate intervention.
Head coach Jack Ross had said last week Josh Doig was "highly likely" to leave Hibs amid reported interest from Watford and Burnley, but with no deal done as yet, the left-back eased back into things. He latched on to Jamie Murphy's pass and centred for Magennis to head in Hibs' second.
And it was a delivery from the opposite side that left County undone again as Doidge applied the finishing touch to Paul McGinn's cross.
Jordan White had headed an early County chance over and Ross Callachan volleyed off target for the visitors.
But they were only fleeting moments of respite for the Highlanders, who were fortunate to avoid a harsher half-time scoreline after Murphy and Doidge went close.
Doidge, who replaced Kevin Nisbet in the starting line-up, had another effort deflected wide during continued Hibs pressure in the second period.
The margin of victory took Ross' side above city rivals Hearts and Aberdeen on goal difference and it is only those three sides with a 100% Premiership record after two games.
Man of the match - Martin Boyle
What did we learn?
If Hibs are to progress in Europe, they will need to show the same clinical finishing that downed their visitors from Dingwall.
The fitness of Nisbet and Paul Hanlon, who was withdrawn with a head knock at the break, are concerns but they go into Thursday's match high on confidence.
Despite a flurry of midweek signings, the visitors started along similar lines to last week's draw with St Johnstone but Jack Burroughs, David Cancola and Harry Clarke were given debuts in the second half. It's still very much a work in progress at County.
What did they say?
Hibernian head coach Jack Ross: "My players were terrific. Just a brilliant afternoon for us. It's a really positive start.
"Martin Boyle's been brilliant since he came to the club. He's as good as anyone in that country in that position when he's in that type of form. Josh Doig was terrific. He's a top player."
Ross County manager Malky Mackay: "We lost an unfortunate goal in terms of the deflection and then there was 10 minutes of madness when we lost another two.
"On another day, we could've lost five or six. Being brave in the second half was something that I asked them to do and something that they did for me."
What's next?
Hibernian travel to Croatia for the return leg of their Europa Conference League third qualifying round tie with Rijeka on Thursday (19:00 BST), then host Kilmarnock in next Sunday's League Cup second-round tie (14:00).
County have a near two-week break until their next match, at home to Rangers on 21 August (15:00), by which time capacity crowds will be permitted again.
