AC Milan now look set to progress to the Champions League last eight after beating Barcelona thanks to Kevin-Prince Boateng and Sulley Muntari goals.
The Rossoneri defended in numbers and the two former Portsmouth players struck twice in the second half.
Boateng turned and fired in following Riccardo Montolivo’s free-kick, before Muntari’s close-range volley nine minutes from time.
Andres Iniesta’s shot was off-target as the Spanish side had a subdued night.
Carles Puyol headed wide following Muntari’s goal, but chances were only occasional for stand-in coach Jordi Roura’s side.
