Pierre-Emerick-Aubameyang

Pierre-Emerick Aubameyang scored on his Arsenal debut but was overshadowed by Aaron Ramsey’s hat-trick in a 5-1 Premier League thrashing of Everton, while former Gunner Alexis Sanchez netted his first Manchester United goal yesterday.

Club record signing Aubameyang immediately rekindled his relationship with former Borussia Dortmund teammate Henrikh Mkhitaryan, also making his home bow, as Arsenal’s new-look front line shone, but it was Ramsey who provided much of the end product with his first career hat-trick. Laurent Koscielny was also on target.

It was Sanchez’s departure that paved the way for Mkhitaryan’s move to the Emirates Stadium from Manchester United, but the Chilean also got accustomed to his new home, scoring at the second attempt after his penalty was saved as Jose Mourinho’s men eased past Huddersfield Town 2-0 at Old Trafford.

Victory moved United to within 13 points of runaway leaders Manchester City, who dropped points for just the fourth time in the Premier League this season in a 1-1 draw at Burnley. Johann Berg Gudmundsson’s equaliser eight minutes from time cancelled out Danilo’s spectacular opener.

A renewed sense of optimism at Arsenal following not only Aubameyang and Mkhitaryan’s arrivals, but also Mesut Ozil’s decision to commit to a new contract this week, exploded in a four-goal salvo in the opening 37 minutes.

Mkhitaryan teed up Ramsey for an early tap-in before Koscielny bundled home Shkodran Mustafi’s flick-on and Ramsey’s long-range effort deflected in off Eliaquim Mangala on his Everton debut.

The moment the Arsenal faithful had been waiting for came eight minutes before the break when Aubameyang chipped home Mkhitaryan’s through ball and the goal was allowed to stand despite the Gabon striker clearly being offside when the pass was played.

Everton restored some pride after the break as Dominic Calvert-Lewin reduced the arrears 25 minutes from time before Ramsey completed his hat-trick to move Arsenal back to within five points of the top four.

Manchester Unitedhad to wait until 10 minutes into the second half to make the breakthrough when Romelu Lukaku got across his marker to volley home Juan Mata’s cross for his 19th of the season. Sanchez was then given the chance to cap his home debut 21 minutes from time when he was brought down just inside the area by Michael Hefele.

And much to his relief, Sanchez tapped home the rebound after Jonas Lossl had saved his initial effort from the penalty spot.

“It was nice for Alexis Sanchez to win a match, the first at home,” added Mourinho. “It was not the goal of his dreams, but it is a goal.”

City were made to rue a host of missed chances, most notably when Raheem Sterling failed to turn Kyle Walker’s low cross into an unguarded net from point-blank range, as Burnley salvaged a valuable point despite seeing their winless league streak extended to nine matches.

Leicester City missed the magic of star man Riyad Mahrez as they drew 1-1 at home against Swansea City. The Algerian hasn’t trained since Leicester priced Manchester City out of a move for Mahrez on transfer deadline day.

Southampton earned their first win since November by edging a thriller 3-2 at West Bromwich Albion to move out of the bottom three.

Brighton also bagged their first league win in seven games, beating West Ham 3-1, while Bournemouth moved up to ninth by coming from behind to beat Stoke 2-1.
