Asked whether his squad – depleted through injury, with Mathieu Debuchy out for up to three months with a dislocated shoulder – could cope without a new signing, Wenger said: “We can, because we have Chambers, Mertesacker, Koscielny. But we have now lost Debuchy, who could play centre-back, Monreal, who can play centre-back, Gibbs as well has been out, of course if we have another injury or two we will struggle. It’s risky. It’s too risky. Of course we have made enquiries and then you have a second handicap of who wants to sell their best players, especially a central defender, in the middle of the season.
