The draw leaves Barcelona top on seven points with Milan in second on five while Celtic are third with three having beaten Ajax 2-1 also on Tuesday.
According to Sport24, although Barcelona started sluggishly into the game, the club's star Lionel Messi proved a thorn in Milan's side by levelling the ninth-minute opener by Milan's Robinho with a decisive goal in the 23rd minute, despite suffering from a thigh problem.
The Italian side has been hit with several injuries with striker Mario Balotelli starting on the bench due to a recent thigh problem, the report added.
