Mikel Arteta claimed Arsenal believe in themselves again after back-to-back away wins over Aston Villa and Leicester put their title challenge firmly back on track.
The Gunners were wobbling after taking only a single point from three games against Everton, Brentford and Manchester City, but Gabriel Martinelli’s strike at the start of the second half was enough to secure a deserved win.
It was a 10th away victory of the campaign for Arteta’s men – one more than they achieved in the whole of last season – and ensured they would head into the next round of matches top of the table.
