AC Milan opened their Serie A campaign on Monday with a 1-0 win at Sampdoria as coach Stefano Pioli fielded a host of new signings including Olivier Giroud.

Giroud, who turns 35 next month, is expected to make a sizeable impact for the Rossoneri alongside the club's other ageing star Zlatan Ibrahimovic.

As the towering Swede recovers from knee surgery, Piolo will hope France's second-highest scorer of all time can make as big an impact as he did at Chelsea, helping the Blues to the Champions League title last season.

With Milan back in the Champions League for the first time since 2013/14, a reliable presence in front of goal could be just what Pioli's team need.

There was a new presence too between the goalposts, with Mike Maignan, recruited from French champions Lille to try to fill the outsize boots of Italy's Euro 2020 winner Gianluigi Donnarumma, now with Paris Saint-Germain.

Looking assured in his new surroundings it was Maignan's long pass that set up the only goal of the game, Davide Calabria then providing the assist with Sampdoria keeper Emil Audero unable to cope with Brahim Diaz's low shot.

The Spanish midfielder joined on loan from Real Madrid last season and that has been extended for two more years.

With Sampdoria marking Giroud out of the game, the French forward was given little chance to open his Milan account.

Towards the end Piolo blooded another of his summer intake, Alessandro Florenzi, who completed his season-long loan move from Roma at the weekend.

In England, West Ham extended their perfect start to the season as Michail Antonio became the club's record Premier League goalscorer with a double in their 4-1 win against 10-man Leicester.

David Moyes' side took the lead through Pablo Fornals' first half goal at the London Stadium. Leicester's Ayoze Perez was sent off for a dangerous stamp on Fornals just before half-time and Said Benrahma bagged West Ham's second after the break before Youri Tielemans got one back for Leicester.

Antonio went into the game tied with Paolo Di Canio on a joint-record 47 goals for West Ham in the Premier League era.

The 31-year-old took sole possession of the record with a brace in the closing stages as West Ham followed up last weekend's 4-2 win at Newcastle with another four-goal blitz.

"I'm really pleased for him. I was disappointed with the way he played in the first half but he did enough to shut the manager up after what I said to him at half-time," Moyes said of Antonio.

Despite a quiet summer in the transfer market, West Ham sit top of the table and look capable of emulating last season's sixth place finish.

The Hammers have won their opening two fixtures of a Premier League campaign for only the second time.
