The Gunners led the English top-flight for much of the 2013/14 campaign before eventually squandering their lead and finishing in fourth place.

Wenger has already signed Alexis Sanchez, Mathieu Debuchy and David Ospina in the summer transfer window, plus the Frenchman is nearing a deal for Calum Chambers.
And the 64-year-old accepted that Arsenal lacked quality at key stages of last season, adding that Arsenal were a couple of games away from winning the title.
“That we were not far [away], it was very tight. We wanted to add that little bit of quality which we missed in the end. It depends on one or two games at the end of the day,” Wenger said.
“There’s 38 games, we finished with 79 points, the winner of the championship had 86 so it was very tight. Hopefully we can get that little bit more quality in the decisive games.
“We were more consistent than everybody else against the lower teams, we performed less well against the top-level teams so that’s what we have to gain.”
