Arsenal boss Arsene Wenger has admitted that his side lacked the quality in the big matches to win the Premier League title last season.
The Gunners led the top flight for the majority of the campaign, but fell away towards the end of the season as they finished in fourth place, seven points behind winners Manchester City.
When asked what he learned from last season, Wenger told reporters: "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.
"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."
Arsenal lost their latest pre-season match to the New York Red Bulls, as Bradley Wright-Phillips scored the only goal of the game.
