Andre Silva is the first AC Milan to score a hat-trick in European competition since Kaka against Anderlecht in 2006

Andre Silva scored a hat-trick as AC Milan began their Europa League campaign by thrashing Austria Vienna.

Silva was signed from Porto for £34m by Milan, who are competing in Europe for the first time in four years.

The Italians spent around £170m in the summer and new recruit Hakan Calhanoglu put them ahead with a thumping drive. Ex-Liverpool player Suso netted the fifth after Silva’s treble.

Defender Alexandar Borkovic powerfully headed in from a corner for Vienna.

Turkish midfielder Calhanoglu – bought for £22m from Bundesliga side Bayer Leverkusen – ran the game for Vincenzo Montella’s side, providing two assists in addition to his goal.

Milan host Udinese in Serie A on Sunday, after being thrashed 4-1 by Lazio in their last domestic outing.
