Arsenal came from a goal down to win their Premier League opener 2-1 against London rivals Crystal Palace.
The managerless Eagles took a shock lead in the 35th minute, with new Palace signing Brede Hangeland heading in a corner after the centre back was left a free man in the box. The Norwegian made no mistake, glancing in a close range header to give the visitors a 1-0 lead at the Emirates Stadium.
Arsenal got the equaliser just before half-time break, when £35million signing Alexis Sanchez wiped in a fantastic free-kick and French defender Laurent Koscielny headed the ball past Julian Speroni to equalise for the Gunners.
It was a reverse of the first goal, with the Arsenal man this time getting the better of his Palace counterpart in the box at the other end.
Arsenal scored the winner in second half stoppage-time after an Alex Oxlade-Chamberlain cross caused confusion inside the Palace box and Mathieu Debuchy had seen an effort parried by Speroni.
Aaron Ramsey was in the right place and the Welshman poked home the ball to secure the three points for Arsene Wenger's side. Palace forward Jason Puncheon had been sent-off moments earlier in the 89th minute after picking up his second yellow card of the match.
Despite the Gunners having the majority of possession they had a rather shaky performance against Palace compared to their marvellous display against Manchester City last week in the Community Shield.
Arsenal found it hard to penetrate the Palace defence and the Gunners once again wasted every corner they were awarded. Another concern for Arsenal was that left-back Kieran Gibbs was substituted for Nacho Monreal in the early stages of the second-half with a suspected injury.
Points on the board
That could expose some problems at the back, but getting the win on the board was the most important factor on the opening day.
