AC Milan coach Rino Gattuso was satisfied with their 1-0 win at Europa League opponents Dudelange.
Gonzalo Higuain proved the matchwinner on the day.
“It's no coincidence that Dudelange are in the group phase, as they beat Cluj on the way here," Gattuso said.
“I liked the attitude of the team, we could've killed it off earlier and it was more of a struggle than I'd have liked, but we got minutes in the legs of many players and we got the result.
“Samu Castillejo doesn't take long to get into shape due to his characteristics. I am happy with how we controlled the game and remembered there is no such thing in modern football as a result to be taken for granted."
