Michu looked to have put the home side on course for a third straight Group A win when he grabbed his sixth goal of the season, and fourth of this European campaign, by sliding the ball beyond Aleksandr Belenov in the 68th minute.
Laudrup said: "We still have some more work to do. We have three very difficult games left, and two of them are away.
"With Kuban it will be difficult with the long hours travelling and the time difference, and then we face a completely different Valencia side from the one we beat in the Mestalla.
"The last game is a tough trip to St Gallen when the weather might be bad.
"We know your home games are very important in this competition, we beat the best team in the group away from home which changed everything, but we still have a home game to come and to have seven points at this stage is very good.
"We can still decide if we move on to the next stage."
