The Milan coach remains upset over the Sulley Muntari goal that was not awarded in their 1-1 draw with Juventus.
“It was an important incident, but it is in the past now,” said former Rossoneri legend Maldini.
“In order to relax and focus on your work, you have to forget. It would be better for both sides to avoid further controversy.
“In 20 days Milan have lost two of their three objectives for the season, going out of the Champions League and Coppa Italia, but the Serie A title race is still open.
“Both Milan and Juve have a 50 per cent chance of winning the Scudetto, because slip-ups are very common this season.”
