Sir Alex Ferguson feels his Manchester United players have been a little too cavalier of late as he looks to strike the right balance between defence and attack.
Basel's second goal in the 3-3 draw on Tuesday night particularly concerned the boss, who knows Norwich will also look to exploit any gaps at the back at Old Trafford on Saturday. The Canaries are in good form and there is no danger of any complacency from the champions, particularly after what happened in the Champions League in midweek.
