AC Milan coach Max Allegri was happy with his new players in victory at Bologna.
Nigel De Jong and Bojan Krkic received their Rossoneri debuts as substitutes, but Riccardo Montolivo went off with a thigh injury.
"De Jong is a player of international level, while Bojan may be young but is already experienced. M'Baye Niang is young and has to grow along with the other lads."
