Leipzig-Schreck Shakhtar Donetsk has missed the next victory in the Champions League.
The Ukrainian top club did not get beyond a 1-1 (1-1) draw against Celtic Glasgow in Warsaw.
The Italian champions AC Milan defeated Dinamo Zagreb 3-1 (1-0) and celebrated their first win.
Celtic took the lead in the Polish capital, where Donetsk plays its home games because of the Russian war of aggression, with an own goal from Artem Bondarenko (11th).
The strong Mychajlo Mudryk (30th), who had already scored 4-1 in Leipzig, equalised.
It was Glasgow's first point in Group F after losing 3-0 to defending champions Real Madrid.
French world champion Olivier Giroud (45th, penalty kick) scored for Milan, as did Alexis Saelemaekers (47th) and Tommaso Pobega (77th) in the 1-1 draw in Salzburg.
Zagreb came through Mislav Orsic (56th), who was still the match winner in the surprising 1-0 win against Chelsea, to the interim 1-2.
