Arsenal boss Arsene Wenger wants to improve his side's defence over the summer. The Gunners conceded 37 goals as they finished fourth in the Premier League in 2008/09, 18 points behind champions Manchester United.
"The last season was very interesting because we had a sloppy start and then we became stronger and stronger," said the Frenchman.
"It has been interesting as well because it is a very young team, but they have been tested mentally.
"The defensive record, that is an area that we want to work on and that we want to improve."
