Robin van Persie feels it is difficult to put into words the reasons why Arsenal failed to deliver silverware again, but maintained it was up to the squad to prove they have what it takes to get over the line next season.
The Gunners 2-1 home defeat by Aston Villa leaves them in real danger of being overtaken by FA Cup winners Manchester City in the race for automatic Champions League qualification.
Since suffering a dramatic last-minute defeat to Birmingham in the Carling Cup final at Wembley, Arsene Wenger's men have recorded just three wins in all competitions as swift exits from Europe to Barcelona and the FA Cup at Old Trafford followed before a total collapse of their Barclays Premier League title bid.
Van Persie - whose late consolation goal took his tally to 21 and was his sixth in the last seven games - accepts Arsenal need to show more courage if they are to turn potential into trophies.
"There were lots of things (which went wrong) - we were not consistent enough. It is difficult to talk about it now," Van Persie told Arsenal TV Online.
"It is going to be difficult to finish third, but we still have one game and have to win that to at least give us a chance.
"Next season we have to try [to come back stronger]. Everyone starts from scratch and we have a chance, it is up to us to prove it."
