Ange Postecoglou hailed his Celtic stars for turning trouble into a potential Treble as they booked a place at Hampden.
The Parkhead team swept Dundee United aside and were immediately rewarded with a colossal Scottish Cup semi-final blockbuster against Rangers.
A double from Giorgos Giakoumakis followed an early Callum McGregor drive on Tayside as the Premiership leaders beat Tam Courts' side 3-0.
Celtic already have the Premier Sports Cup in the bag and after a rocky start are now fighting to make it a cup and league clean sweep.
Postecoglou said: “At the start it was all trouble, now it is all treble.
“The important thing is that we are still in the competition and at this stage of the season we have given ourselves an opportunity for success.
“That is the expectation here. That expectation is on me and everyone at the football club. The players need to embrace that.
“We can’t think just because we have won a trophy already that it is going to be a good season.
“We want to win every competition we are in and give ourselves a chance to do that.
“Particularly at this end of the season and we have given ourselves a chance. It should also help with the confidence.”
Celtic beat Rangers last time out in the league and the Hoops manager knows this will be an even bigger one.
He stated: “We're in the semi-finals and we've got Rangers so on we go.
"It will be massive. That was the prize on offer, to get through you've got a semi-final at Hampden and irrespective of who you play it's going to be a massive game.
"That's the reward for a really good performance by the boys tonight.
Celtic could face Rangers three times next month in games that could make or break their success on the final two domestic fronts.
Postecoglou said: “Mate, they're just games of football you need to win. The most important thing is that we're putting ourselves in a position where those games mean something. We focus on the next challenge and don't look too far ahead.
“It's going to be great. It will be a cracking atmosphere. I've had two trips to Hampden and in both those games the atmosphere was unbelievable. I'm sure it will be a great atmosphere again for that semi-final but we've got a few games before that to focus on.”
Celtic took their unbeaten run to 30 domestic games and their boss knows they will need to keep their foot to the floor in the run-in.
Postecoglou added; “We're going okay, but the key thing now is to finish our stuff off. We're in a position now where we can challenge.
“There's still eight games to go in the league. We've just got to tackle each challenge the best way we can. We're getting players back and our training's really good - they're the kind of things we need to focus on.”
Celtic are also on a roll away from home and Postecoglou insisted that has been big.
He admitted: “It's the main factor in our form. After a rocky start, our away form has been outstanding.
“We've been to Edinburgh four times, Aberdeen twice, Livingston twice, we've come here again - all tough away fixtures - and the boys have handled it really well.
“Away from home we're still controlling games and trying to be the team that takes it to the opposition. We don't take it for granted winning away - it's not easy away from home. Being able to handle that has probably been the most important part of our season. “
