Arsene Wenger hopes fans 'respect' Robin van Persie

Arsene Wenger hopes there will be a "respectful" reception from Arsenal fans who will see their former captain play against the Gunners in Manchester United shirt for the first time on Saturday.

The Arsenal manager also says a strong performance at Old Trafford will be important for the "belief" of his side, following a Premier League defeat to Norwich and an "irrational" 7-5 midweek win at Reading in the League Cup.

Wenger also comments on Theo Walcott's unresolved contract situation, insisting there is an "urgency" at the club to have it sorted out before Christmas.
