Arsenal have made one change from the team which defeated Newcastle United 3-0 on Monday night for today's match against West Brom, Mathieu Flamini replaces Aaron Ramsey, who is left out of the squad.

One player who makes the Arsenal squad - and hoping to make his first appearance for the club since 16 March 2013 - is Abou Diaby. The French midfielder had been sidelined with a cruciate ligament injury.

With fourth place now assured after Everton's 3-2 loss against Manchester City on Saturday, manager Arsene Wenger must have one eye on the FA Cup final on 17 May, when they take on Hull City.

West Brom, meanwhile, make two changes, Diego Lugano and James Morrison come in.

Arsenal: Szczesny, Sagna, Mertesacker, Koscielny, Monreal, Flamini, Arteta, Cazorla, Ozil, Podolski, Giroud

WBA: Foster, Dawson, Lugano, Olsson, Brunt, Amalfitano, Mulumbu, Morrison, Dorrans, Sessegnon, Berahino
