Arsenal boss insists defence does not need overhaul

Arsene Wenger continues to believe that Arsenal's defence is not their Achilles heel. Many have pointed to a continued lack of defensive stability as the reason Arsenal's bid for a first trophy since 2005 floundered again last term. The Gunners leaked 43 Premier League goals - 10 more than rivals Manchester City and Chelsea - yet Wenger said after his team's arrival in Asia this week that they do need to change their footballing philosophy . The Frenchman feels Arsenal merely need to improve their attacking qualities, making no reference to his side's defence, and he maintains that major surgery at the back is not needed. "I don't think we are weak defensively, but we are an offensive team," he said."Sometimes that exposes our defenders a bit more than other teams." Wenger has been linked with Bolton centre-back Gary Cahill and Werder Bremen's Germany international Per Mertesacker but a defensive addition at the Emirates this summer does not appear to be a certainty. "I believe we have quality defenders," Wenger added. "One is Thomas Vermaelen and he did not play last year. "In open play, we were one of the better defences [last season], but we conceded too many goals on set-pieces and that is where we want to improve this season." Arsenal beat a Malaysia XI 4-0 on Wednesday night and have arrived in China for the final leg of their Asia tour, which sees them face Hangzhou Greentown on Saturday.
