AC Milan moved to within three points of fourth placed Atalanta with an unconvincing victory over Bologna in an ill-tempered affair which contained three red cards on Monday night.
During an entertaining first half, Milan centre-halves Cristian Zapata and Mateo Musacchio put free headers wide shortly before Gianluigi Donnarumma superbly stopped Riccardo Orsolini's one-on-one effort to keep the scores level.
The hosts took the lead in the 37th minute when former Liverpool winger Suso cut inside on his left foot to powerfully beat u0141ukasz Skorupski at his near post, much to the relief of an increasingly restless San Siro crowd.
