Villa stun Arsenal, Mignolet saves Liverpool

Arsenal endured a calamitous start to the English Premier League season after conceding two penalties and having Laurent Koscielny dismissed in a 3-1 home defeat by Aston Villa on Saturday.

Christian Benteke, Villa's top scorer last season with 19 goals in his debut campaign, was the architect of Villa's shock win, scoring twice to puncture the pre-season optimism at the Emirates Stadium.

Olivier Giroud gave Arsenal a sixth-minute lead by clipping home a left-wing cross from Alex Oxlade-Chamberlain, but Benteke equalised in the 22nd minute.

Arsenal goalkeeper Wojciech Szczesny was penalised for tripping Gabriel Agbonlahor and although he redeemed himself by parrying Benteke's spot-kick, the Belgian striker reacted alertly to head in the rebound.

Benteke put Villa ahead from the spot with just under half an hour to play after Koscielny was adjudged to have fouled Agbonlahor, and the Frenchman's misery was compounded moments later when he was shown a second yellow card for an untidy lunge at Andreas Weimann.

Spanish close-season signing Antonio Luna completed victory for Paul Lambert's side with five minutes to play, running clear and coolly wrong-footing Szczesny.

Everton draw, Lambert's dream week continues           Elsewhere, Roberto Martinez began his career as Everton manager by picking up a point from an entertaining 2-2 draw at Norwich City.

Quick-fire goals from Ross Barkley and Seamus Coleman put the visitors in front after Steven Whittaker had given Norwich the lead, only for £8.5m record signing Ricky van Wolfswinkel to equalise for the home side with a fine header in the 71st minute.

Rickie Lambert, who scored the winning goal against Scotland on his England debut in mid-week, completed a memorable few days by snatching a 1-0 win for Southampton at West Bromwich Albion with a last-minute penalty at the Hawthorns.

Cardiff lose opener, Mignolet saves Liverpool       Meanwhile, Cardiff City made a disappointing return to the top flight following a 51-year absence after goals from Joe Cole and Kevin Nolan saw them beaten 2-0 at West Ham United, while a 52nd-minute header by Pajtim Kasami gave Fulham a 1-0 win at Sunderland.

Earlier, Simon Mignolet saved a last-gasp penalty to earn Liverpool a 1-0 win over Stoke City in the opening game of the new season at Anfield.

The Belgian goalkeeper, a £9m signing from Sunderland, parried Jon Walters' 89th-minute spot-kick and then brilliantly blocked Kenwyne Jones' follow-up after Daniel Agger was penalised for handball.

The game, the first domestic league match in the world to be played with goal-line technology in place, was ultimately decided by a low 20-yard strike from Daniel Sturridge in the 37th minute.

Liverpool's fluid forward line of Sturridge, Philippe Coutinho and debutant Iago Aspas impressed in the absence of the suspended Luis Suarez, but it was Mignolet who proved the hosts' saviour.

"We bought him because he is a top, top goalkeeper and he had three saves to make in total," Liverpool manager Brendan Rodgers said. "I thought overall our performance was outstanding."

Van Persie, Welbeck give Moyes dream start
David Moyes praised Manchester United for a clinical performance after a 4-1 win at Swansea City on Saturday in his first Premier League game as manager.

Robin van Persie and Danny Welbeck each scored twice, Wilfried Bony replying for the hosts, to send United to the top of the fledgling standings.

Asked if it had been a dream start to his Old Trafford tenure, Moyes told Sky Sports: "It is, because you always want to win your games and when you're manager of Manchester United, the job is to win the games."
