Arsenal avoided further embarrassment after coming back from a goal down to win 3-1 over League Two side Shrewsbury in the Carling Cup.

The Emirates Stadium was stunned when on 16 minutes the visitors took the lead through James Collins who headed in Marvin Morgan's cross.

However, it served as the wake-up call Arsenal desperately needed and 15 minutes later they clawed their way back through Kieran Gibbs whose far post header from Carl Jenkinson's cross, crept in.

Alex Oxlade-Chamberlain scored the decisive second, his first goal from his first start,as he drilled in powerfully on the hour-mark.

Yossi Benayoun also got his first goal for Arsenal, sparing his boss Arsene Wenger a frantic finale, calmly finishing with 12 minutes remaining.
