No matter how good the Gunners coach is, he cannot turn the centre-backs into good defenders and must find better options, says the ex-midfielder
Arsenal will continue to struggle defensively as long as they have David Luiz and Sokratis Papastathopoulos in the starting XI, Roy Keane says, because the pair are 'not good' centre-backs.
The duo have been the preferred pairing for Unai Emery this season, but the Gunners have not kept a clean sheet in any of the five Premier League matches they have completed so far.
Arsenal had conceded 10 times while both the Brazil and Greece internationals have been on prior to Tuesday, with their only clean sheet came in the opening game of the campaign - when Calum Chambers partnered Sokratis in the middle of the back line.
