Milan extended their 100 per cent start to the Serie A season with a 3-0 win over newly-promoted Spezia at San Siro on Sunday. 

Six players kept their places after Thursday's penalty shoot-out win over Rio Ave in the Europa League, and a lack of freshness was apparent in the first half, with Milan struggling to break down their less illustrious opponents. 

They looked sharper at the start of the second period, though, and duly went ahead shortly before the hour mark when Rafael Leao prodded home from close range. 

Theo Hernandez added a second in the 76th minute before Leao made sure of all three points with another predatory strike two minutes later, as Milan made it three wins from three.

After a largely dismal opening period, the game burst into life on the stroke of half-time. 

First, Alexis Saelemaekers blazed over from 15 yards after being teed up by Davide Calabria, while at the other end Gianluigi Donnarumma pawed away Daniele Verde's powerful strike. 

Milan belatedly woke from their slumber at the start of the second period and were rewarded with the opener 12 minutes after the resumption when Leao stole in at the back post to stab home Hakan Calhanoglu's teasing free-kick. 

Donnarumma made a smart stop from Kevin Agudelo before Hernandez doubled Milan's advantage, the French full-back racing forward from just inside the opposition half and drilling past Rafael from 15 yards. 

That knocked the stuffing out of Spezia and Milan added a third shortly after when Leao met Franck Kessie's headed knock-down with a simple finish inside the six-yard box to wrap up an ultimately routine win.
