You have to wonder what was going through the minds of the Arsenal hierarchy over the summer when they belatedly decided that David Luiz was the answer to their defensive issues. There is no doubting the positives of the Brazilian’s play; David Luiz can change games with his passing and prowess in the opposition box but his propensity for switching off is there for all to see. Unai Emery played three defensive midfielders at home against Tottenham, and one suspects he has limited faith in his defence, as proved by the counterattack for the opener, which saw David Luiz wander off and an unmarked Christian Eriksen tap into an empty net after a goalkeeping error. At least January is not too far away and Arsenal can plan once more to solve their problems, preferably not with a deadline-day signing. Will Unwin
