Arsene Wenger praised his side's character in a hostile environment at Red Star Belgrade as they took a step towards the Europa League last 32. Olivier Giroud scored a fantastic late winner as Arsenal edged to their third straight Europa League win by beating 10-man Red Star Belgrade 1-0 in Serbia on Thursday. Arsene Wenger's men rode their luck at times, before Giroud struck in the 85th minute after Red Star had seen Milan Rodic sent off. The Premier League side stay top of Group H, five points clear of Red Star, while Cologne remained pointless after losing 1-0 at BATE Borisov.
