Laurent Koscielny v Callum Wilson
Wilson has the ability to turn it on with a bit of pace and if given room he can finish so Laurent Koscielny needs to be at it once again. The Frenchman has seen his German central partner Shkodran Mustafi leave him in trouble at times this season so he may have to contend with that too against the Cherries’ prime threat. Keep Wilson out of the game, though, and Arsenal should be able to assert themselves.
