Next week's home match against PSG and the trip to RB Leipzig means the manager is not getting ahead of himself.
"The group is still very open," the Norwegian said.
"We've got nine, two on six points (PSG and RB Leipzig) and Basaksehir on three, so we still need points to go through.
"One probably should be enough and three probably gives you the win, so hopefully against PSG we can secure the points we need but that's another matter.
"Of course I thought the whole team played really well. We found our positions and the tempo with the ball was really good.
"We deserved the win, of course, after that first half. Second half is always different and more difficult to keep the tempo when you're winning 3-0."
