Arsenal ensured qualification to the Champions League knockout stages this evening after a comfortable 3-1 victory over Partizan Belgrade in Group H. Robin van Persie put the hosts ahead from a spot-kick early on before they suffered a slight scare when Serbian visitors Partizan levelled early on in the second half thanks to Brazilian striker Cleo. However the Gunners held their nerve and regained the lead through Theo Walcott whilst Samir Nasri added a third to put qualification beyond doubt for Arsene Wenger’s men.
