Ange Postecoglou insists Celtic don't need to tighten up defensively ahead of Thursday's trip to face Bodo/Glimt.
And he's dispelled the "myth" that there is any such thing as the perfect gameplan as his side get set to mount a Europa Conference League comeback.
The Premiership leaders travel to Norway to face the Eliteserien champions and have a mountain to climb after their shock 3-1 defeat at Parkhead.
It was a rare black spot on their otherwise formidable recent record and they need a big performance in the second leg to keep their European ambitions alive.
Postecoglou admits his side need to be more clinical with Daizen Maeda's strike their only goal from 16 shots at Celtic Park.
But he stopped short of criticising his team's defensive shape - insisting he won't be changing his set-up for Thursday's vital clash.
He was asked at his press conference if he will set his team up more conservatively in Bodo and his answer was characteristically frank.
He said: "No, because that would be changing, which is what I said we don't do.
"The perfect game plan only exists in a mythical land well beyond my comprehension.
"We'll play our football. We played our football the other night, they were more clinical than us but we've been clinical this year in terms of scoring goals.
"We weren't as efficient in our front third in terms of chances, they were. So if that changes, we're in a better shape.
"We don't need to be more solid defensively. If they had 20 chances, hit the crossbar and Joe made 15 saves, I'd be saying we have some issues defensively.
"That's what I focus on. I look at the performance and the way we play. They were a lot more clinical with their fewer attempts on goal, obviously we need to improve that but it's not something that's been ongoing.
"Our approach has to be the same, just go out there and play our football with no 'buts' in it at all."
