Arsenal defender Mathieu Debuchy has been handed his first start for three months in the FA Cup semi-final with Reading.

Debuchy has been sidelined with a shoulder injury, but his inclusion is one of four changes made by manager Arsene Wenger.

Wojciech Szczesny, Kieran Gibbs and Danny Welbeck all start, with David Ospina, Hector Bellerin, Nacho Monreal and Olivier Giroud making way.

Reading boss Steve Clarke has made two alterations to the side that lost 1-0 to Bournemouth in midweek.

Danny Williams and Pavel Pogrebnyak have returned to the starting lineup, with Jem Karacan and Nathan Ake dropping out.

Arsenal: Szczesny, Debuchy, Mertesacker, Koscielny, Gibbs, Coquelin, Ramsey, Cazorla, Ozil, Alexis, Welbeck
Subs: Ospina, Gabriel, Monreal, Flamini, Wilshere, Walcott, Giroud

Reading: Federici, Gunter, Pearce, Hector, Obita, Williams, Chalobah, McCleary, Robson-Kanu, Mackie, Pogrebnyak
Subs: Anderson, Kelly, Cooper, Karacan, Norwood, Cox, Yakubu
