Atalanta failed to secure a win against Udinese, resulting in their bid for Champions League football taking a hit on Saturday.
Nigerian forward Ademola Lookman was unable to make a significant impact during the match, with Atalanta producing an uninspiring performance against their off-form opponents.
The draw kept Atalanta in sixth place, five points behind Italy's top four. The hosts had a chance to win in the final minute of the match when Rafael Toloi attempted a dipping strike, but it was brilliantly saved by Udinese's Marco Silvestri.
Meanwhile, AC Milan, who will move to second place with a win at Fiorentina, honoured former Fiorentina captain Davide Astori, who passed away five years ago on this day. Udinese is currently in ninth place, level on points with Monza, who beat Empoli 2-1 in Saturday's early match.
