The Gunners manager is toying with the idea of playing with five defenders, similar to the formation Roberto Mancini has tried to introduce at Manchester City this season.
Wenger planned on making the switch for last week’s Champions League clash against Schalke after his side’s defensive troubles during the 2-1 defeat against Manchester United.
The Frenchman held a training-ground meeting to discuss the idea with his coaching staff.
It was eventually decided there was not enough time to implement the system on the training field ahead of the clash in Gelsenkirchen.
But it is understood the change of formation is still very much in the forefront of Wenger’s thoughts as his side continue to struggle defensively.
When Arsenal’s first-choice defenders are fit, the back five would consist of: Bacary Sagna at right wing-back, Laurent Koscielny, Per Mertesacker and Thomas Vermaelen as the three central defenders and Kieran Gibbs as left wing-back.
Whether or not Wenger and his coaching team decide to press ahead with the change remains to be seen, but the mere fact he is considering such a shift in tactics underlines how concerned he is by the club’s creaky back line.
The Frenchman will have just two days to prepare his side for Saturday’s crucial North London derby due to the international break, which will cause major problems in trying to reshape his defence in time.
However, after conceding just one goal in their opening four games, the Gunners have shipped 15 in their last seven outings and Wenger knows improvements have to be made to rectify the problem.
Wenger admitted his defence looked ‘fragile’ after Saturday’s 3-3 home draw against Fulham.
And the 63-year-old will hope to have first-choice keeper Wojciech Szczesny and Gibbs back for Saturday’s clash against Andre Villas-Boas’ men as he looks to shore up his defence.
Meanwhile, Theo Walcott, who pulled out of the England squad with a glute injury, is expected to be fit. -DailyMail
