It was a disaster this seasonQuote:
JACK WILSHERE admits it will be a "100 per cent disaster" if Arsenal don't win a trophy next season.
And the England playmaker insists The Gunners must toughen up to compete for the big prizes.
Wilshere, 19, was shocked at how his side finished potless and also fell away to fourth in the Premier League - whichmeans they have to pre-qualify for the Champions League.
He believes they are too soft and even suggested they should follow Manchester United's example by arguing with officials when they don't like a decision.
As he prepared for his final game of the season for England against Switzerland at Wembley on Saturday, Wilshere said: "It will be a 100 per cent disaster if we don't win a trophy next season.
"We know that. The fans feel it. We feel it. We just need to win a trophy.
"Arsenal are a big club and we need to be winning trophies. We need to win them to keep our big players.
"We must be more aware and have a bit more aggression. We've got some players that can do that but we have to go as a team."
Wilshere believes one of Arsenal's problems is they accept referee's decisions too easily - unlike their rivals.
He added: "It's no use just Robin van Persie going because it looks like it's just him having a go at the ref. If we all get round him...
"You just see the other teams do it and you think 'we need to do it as well'. Man United are the best at it. They get round the referee.
"We have to be more of a team and be more aggressive and show more authority."
