Arsenal midfielder Mathieu Flamini believes the Gunners' reshaped squad will have more staying power in the new season's Premier League title race.
Flamini said Arsenal -- who followed their FA Cup win over Hull in May by lifting the Community Shield at Wembley with a 3-0 win over Manchester City on Sunday -- had "collapsed" in the latter stages of last season's league challenge.
But the Frenchman suggested summer arrivals Alexis Sanchez, Mathieu Debuchy and Calum Chambers would help transform their prospects.
"Last season was good for us, even though we did collapse [in the league] over a couple of months," Flamini told the official Arsenal website.
PREMIER LEAGUE PREVIEWS
As we count down to kickoff on Aug. 16, ESPN FC previews all 20 teams in this season's competition. Can Burnley, QPR and Leicester stay up? Will the new signings of Alexis Sanchez, Diego Costa and Adam Lallana help usurp Man City's crown? Will Manchester United get back on track under Louis van Gaal?
"Now we are ready, with a strong team that has a lot of quality to be able to fight to the end.
"We have signed a few really good players -- and that is excellent for us, because we have added a lot of quality to the team. We were already strong last season, but now we have added even more.
"To win another title [the Community Shield] after the FA Cup is obviously very positive for us, and shows that we are going in the right way.
"Of course this will be good for the confidence to start the season, but we have to be focused because the season will be a long one. We have to make sure that we keep going until the end."
Arsenal start their Premier League campaign with a home game against Crystal Palace on Saturday.
