It remains goalless at the break between Anderlecht and AC Milan at the Constant Vanden Stock Stadium.
The hosts should have taken the lead in the 14th minute when Milan Jovanovic was put clean through, but he was denied by Christian Abbiati.
Lucas Biglia nearly curled the ball in from a corner in the 35th minute, but Kevin Constant was able to hack the ball off the line.
Milan struggled to find any rhythm during the first period and Massimliano Allegri may have some stern words for his players during the break.
