Arsenal manager Arsene Wenger maintains he knows what must be done over the summer to turn the Gunners into champions next season.

It has been seven years since Patrick Vieira's Invincibles lifted the Premier League trophy, with any slim title hopes extinguished in brutal fashion with a 3-1 defeat at Stoke on Sunday.

Arsenal's defensive frailties were exposed again at the Britannia Stadium - most notably when an unmarked Kenwyne Jones bundled home Stoke's opener and also for the third goal following an awful clearance from Johan Djourou which fell straight to Jon Walters, the blunder coming moments after Robin van Persie scored his 20th goal of the season to give the visitors brief hope.

Wenger has been urged to bring in experienced heads during the summer, most notably to help shore up the defence, with the likes of Blackburn's Chris Samba and Bolton's Gary Cahill both reported targets.

However, the Arsenal manager insisted now was not the time to talk about what is missing as his team regroup for next weekend's clash with Aston Villa looking to stay ahead of Manchester City in the race for automatic Champions League qualification.

"We have our plans and we know what we will do," said Wenger. "It is not the best moment to analyse after a disappointing game, but if you analyse all competitions and how we have done, the number of games we have played, then we have done well.

"We have to take a little bit of distance and make the right analysis of the season."
