Arsene Wenger believes Arsenal need 'a little bit extra' if they are to effectively challenge for the Premier League and Champions League next season.
The Gunners finished four points adrift of eventual champions Manchester United in the league and were knocked out of Europe at the last eight stage by Liverpool after a tight quarter-final tie during a third straight trophyless season.
But Wenger has denied claims that he needs to make dramatic changes to his squad in the summer if he is to secure either of the two main prizes on offer.
He told Arsenal TV Online: "We have to realise we were very close to winning both (the Premier League and Champions League) and that we have to come back to get that little bit extra which makes us winners of both competitions.
"We have made a tremendous improvement and want to develop - the average age of our team is very young and we can only be better if we have the right spirit next year.
"The team gained a lot of experience with our disappointments. Suffering makes you more mature and that is why I think at the start of next season you will see a team which is much more mature in its behaviour.
"If we can add a bit more experience and talent, that is even better."
