Arsene Wenger says managers must be "careful" when criticising their own players and "control what you say".

Wenger's Arsenal side come up against Jose Mourinho's Manchester United on Sunday, battling to reach the Premier League's top four places.

Mourinho has questioned the desire of defenders Luke Shaw, Chris Smalling and Phil Jones to return from injury.
