Morgan Gibbs-White had the perfect opportunity to give his side a 1-0 lead from the penalty spot in the 35th minute, but his effort was well saved.
Forest didn’t create much after ending the game with nine totals shots and an xG of just 1.41 that and were held to a goalless draw by the Austrian champions at the Merkur Arena.
Speaking to reporters after the game, Dyche couldn’t help but admit to his frustration at not being able to get the win.
“I think it’s both frustration and being pleased with a point,” Dyche said. “We’re obviously threadbare.
“We’ve had players playing who ideally you wouldn’t just throw into a game like this – you’d try to give them games away from this sort of competition to get them ready. More so with Kali (Arnaud Kalimuendo); he's been thrown in at the deep end a little bit.
“We were limited with changes from the bench. We would have preferred to have made more changes earlier in the game.”
He added: “On the other hand, the frustration side of the performance is that we created so many good chances, more so in the first half.
“They're golden chances, they're chances that change the whole feel of the game because we were dominant and we're playing some decent stuff.
“We were affecting the game, looked a threat from set-pieces, looked a threat from open play and the whole feel changes when you score goals. And we didn't.
“That's the frustrating part because I think overall we should come away from here with a win. I thought that was clear from the performance, in my opinion.”
