Arsenal and Manchester City are set to lead the chase for promising Toulouse defender Serge Aurier, [football] direct news understands.googletag.cmd.push(function() { googletag.display(“div-gpt-ad-1389116196215-0”); });The 21-year-old has been in superb form in Ligue 1 this season, showing tremendous ability as either a central defender or right-back, putting in some solid displays at the back and also contributing going forward with two goals and four assists. The Gunners were first linked with Aurier in January, though they instead focused their efforts on bringing in attacking players such as Julian Draxler and Mirko Vucinic, though to no avail. City may now provide some stern competition for the Ivorian’s signature, as Manuel Pellegrini also eyes defensive improvements to his squad for next season. As the likes of Micah Richards, Matija Nastasic and Joleon Lescott may all leave the club, Pellegrini has identified Aurier as a good, versatile option at the back. Arsenal could also be set to lose key players in Bacary Sagna and Thomas Vermaelen, and Arsene Wenger will hope to lure another top talent from French football to the Emirates Stadium.
