Arsenal goalkeeper Wojciech Szczesny says fans have the right to boo their own players - and manager.

The Gunners boo-boys were in full voice after boss Arsene Wenger substituted Alex Oxlade-Chamberlain for Andrey Arshavin during the 2-1 home defeat to Manchester United on Sunday.

Even skipper Robin van Persie seemed to disagree with the decision, with the striker pictured mouthing 'Oh no' as the change was being made.

Goalkeeper Szczesny said: "They're entitled to their opinion and they show it in the way they do. That's fine with me."
