ARSENE WENGER last night tore into his struggling Arsenal team. The Emirates boss hopes to avoid Carling Cup humiliation at home to Shrewsbury tonight with his side having leaked 13 goals in four matches. Asked to explain Arsenal's nightmare defensive record, Wenger said: "A lack of concentration, a lack of communication, a lack of co-ordination and individual urgency." Own goals from Alex Song and Laurent Koscielny played a big part in Saturday's 4-3 disaster at Blackburn. Wenger added: "When you score an own goal, you have to look at yourself. It is never completely out of your reach where you have no chance at all. "Our season depends now on how well we respond to this disappointment and how quickly we can cut out the mistakes we made on Saturday by giving away goals that we should never give away. "The Blackburn game was very disappointing and frustrating. "I must say that the disappointments and frustrations are huge. We feel we gave that game away, not that we have lost the game. There is nothing worse in our job than having that feeling." Wenger will ring the changes for tonight's clash against Shrewsbury, who are bringing down 5,000 fans. Alex Oxlade-Chamberlain, who joined from Southampton in a deal worth up to £15m, will make his full debut. So will Japanese rising star Ryo Miyaichi while Ju Young Park, who arrived from Monaco for £1.8m, will also feature. Wenger said: "We need to find the right mixture in this competition between keeping our faith in young players and winning the games." THE SUN
