ARSENAL overpowered London rival Chelsea 3-0 at the Emirates Stadium on Saturday to mark Arsene Wenger’s 20th anniversary as Gunners boss in style.

    Earlier, Manchester United thrashed defending Premier League champion Leicester City 4-1 to vindicate manager Jose Mourinho’s decision to drop Wayne Rooney while Manchester City maintained its perfect start with a 3-1 win at Swansea City.

    Arsenal scored twice in three minutes against a Chelsea defense missing injured captain John Terry with an ankle injury.

    The Gunners were 1-0 up in the 11th minute when Alexis Sanchez robbed center-back Gary Cahill and chipped the ball over goalkeeper Thibaut Courtois.

    Minutes later it was 2-0 when Theo Walcott finished off a slick Arsenal passing move.

    Arsenal, which hadn’t beaten Chelsea in nine matches, was 3-0 up in the 40th minute when Mesut Ozil and Sanchez exchanged passes before the former volleyed home.

    “It was an outstanding team performance,” Wenger told the BBC. “We played with spirit and collective pace and movement.”

    United scored four goals, three from set-pieces, as Chris Smalling, Juan Mata, Marcus Rashford and Paul Pogba — with his first goal since his return from Juventus — were all on target between the 22nd and 42nd minutes at Old Trafford.

    England skipper Rooney was limited to a few minutes off the bench but Mourinho told Sky Sports: “Wayne Rooney is a big player for me, United and this country.”

    Leicester managed a brilliant consolation goal from half-time substitute Demarai Gray but that could not stop the Foxes shipping four goals for the second time in as many away league games after doing so at Liverpool a fortnight ago.

    Sergio Aguero marked his return from a three-game ban for a wayward elbow as Manchester City won 3-1 away to Swansea — the second time in a week they had triumphed at the Liberty Stadium after their EFL Cup victory over the south Wales side.

    Aguero fired City into a ninth-minute lead but Swansea was level minutes later when Fernando Llorente lashed in a half-volley. City, however, regained the lead with an Aguero penalty in the 65th minute after Mike van der Hoorn fouled Kevin De Bruyne in the box. (SD-Agencies)
