Atalanta wasted several excellent goalscoring chances as they were held to a Champions League stalemate by a resilient Slavia Prague side in Bergamo.
Prior to Wednesday evening, only two matches in this year's league phase had ended 0-0, both involving Pafos.
The hosts only had themselves to blame for their failure to take all three points against opponents who had lost nine of their previous 10 matches against Italian sides.
Ivan Juric's team created enough opportunities to win several matches but were left to rue some errant finishing against the Czech champions.
Montenegrin forward Nikola Krstovic was unable to convert two glorious opportunities in a two-minute spell just before the half hour mark, while Ademola Lookman dragged one effort wide and had another deflected behind when well placed.
Slavia, who have not won a game in the competition since September 2007 - a run of 14 matches - briefly threatened to pull off a famous victory with Michal Sadilek and Tomas Chory both having chances on the break.
However, in the closing stages Atalanta piled forward and substitute Gianluca Scamacca, making his first appearance after injury since August, headed over from close range and then had a thumping drive well saved by Jakub Markovic.
