Robin van Persie maintains Arsenal need to "toughen up" next season.
The Gunners saw another campaign end without a trophy - the fifth in succession - as Arsene Wenger's men failed to last the distance both in the Barclays Premier League title race and Europe.
While some of that was down to the loss of key men like Van Persie and captain Cesc Fabregas - again linked with a move to Barcelona - at various stages to injury, on more than one occasion Arsenal also could not produce a big performance when it really mattered.
After overcoming defeats to Manchester United and Chelsea to force themselves back into contention, what would have been crucial points were thrown away at Birmingham, followed by away defeats at Tottenham and then Wigan - where they had led 2-0 with only 10 minutes left.
Van Persie - who returned to action at White Hart Lane in mid-April after some five months on the sidelines because of a serious knee injury - feels the Gunners need to make sure they can emulate the courageous effort shown in getting results at places like Stoke and Hull if they are to produce another serious title challenge.
"I just think we need to toughen up," the Dutchman declared.
"We need to make it clear to people: 'if you want to play football, we can play football. If you want to play hard, we can play hard.'
"We can do that, we have it within ourselves, but we need to do it consistently - because if we don't, we lose points and give the wrong message."
