Arsenal legend Freddie Ljungberg has opened up on the one weakness he feels the Invincibles had under Arsene Wenger.
The Gunners created history in the 2003-04 season when they went a full league campaign unbeaten, a feat that has not been matched before or since in the Premier League era.
Ljungberg played a key role in that side, but admits they weren't unstoppable, and has pointed out a weakness that was exposed by Chelsea when Jose Mourinho took over the Blues in 2004.
'One main weakness was if I sometimes came out here, wide right, and people said "Oh, cross the ball, Freddie, you're free just cross it",' Ljungberg explained on Monday Night Football.
