Episode 399 - Who is this Theo Walcott kid?

In this week's Arsecast I find it difficult not to laugh at Diego Costa, because who doesn't want to laugh at Diego Costa? I'm also joined by Rory Smith to discuss this latest iteration of Theo Walcott and how, perhaps, some clarity as to where he plays is helping him perform. We also discuss the fluid front four, and Arsene Wenger as he comes up on 20 years as manager of Arsenal. We touch on his legacy at the club and in English football, and there's all the usual waffle too - as well as 1-day Fantasy Football with FanDuel.
