Cristiano Ronaldo denied the hosts a first-leg lead after a questionable spot-kick was awarded in injury time
Stefano Pioli was angered by the late awarding of a penalty to Juventus as his AC Milan side had to settle for a frustrating 1-1 draw in the Coppa Italia semi-final first leg at San Siro.
Ante Rebic's volley just after the hour deservedly put Milan ahead and preceded a red card for Rossoneri full-back Theo Hernandez.
It took until injury time for Juve to make the most of the extra man with Davide Calabria harshly pinged for blocking Cristiano Ronaldo's acrobatic effort with his arm in the area.
