I agree that he needs to strengthen the first team, but how easy is it?
Arsenal have Cech
Chelsea have Falcao and Begovic (minus Cech)
City have Sterling and Delph
Liverpool have Firmino, Milner, Benteke and a bunch of guys I'm not bothered to recall (minus Sterling)
United have Schweinsteiger, Schneilderin, DePay, Darmian (minus RVP, Falcao)
From that group, United are the ones who have strengthened most, but I'm not seeing a banner summer from any of the top teams, certainly not in line with the promises of EPL strength versus other leagues. Yes, Wenger needs to step it up, but it's probably not that easy right now
