Unai Emery was delighted to see his Arsenal side beat north London rivals Tottenham 4-2 in the Premier League on Sunday – but quickly shifted his focus to Wednesday’s clash with Manchester United at Old Trafford.

The Gunners extended their unbeaten run across all competitions to 19 games as they emerged triumphant in a topsy-turvy local dust-up at Emirates Stadium.

Pierre-Emerick Aubameyang’s first-half penalty initially gave the Gunners the lead, but Spurs were ahead at the break thanks to an Eric Dier header and a spot-kick from Harry Kane.

Arsenal went through the gears during the second-half, however, with Aubameyang grabbing his second of the game before Alexandre Lacazette and Lucas Torreira sealed all three points for Emery’s side, who have also leapfrogged Spurs in the league table.

However, the Gunners do not have long to reflect on their derby day success, as they are back in league action on Wednesday when they travel up north to take on United.

Arsenal have not won at Old Trafford since 2006, but Emery is upbeat heading into the contest.

“We know it’s very difficult in Manchester – in history and in the present,” Emery told reporters. “We want to prepare in the best possible way to have the best performance. This is a big challenge for us and we want to have challenges like Wednesday.”

The Gunners are priced at 3.00 to secure all three points on Wednesday, while United, who have failed to win any of their last three league games, are available at 2.38 and the draw is on offer at 3.50.
