You do know Ayew was born in France? I love Ayew, one of my favourite players alongside Prince from Milan but he has no place in our squad due to him being an attacker for the left side, the right side isn't natural to him at all. Mata's stamina is also underrated. IIRC he was the most played player for us last season! To say Ayew has twice more stamina is quite funny. Regardless, back on topic now, Azpilicueta is probably the best signing we could make. We need a replacement for Bosingwa, who played over thirty games last season if I'm not incorrect, and Azpilicueta can fill in that void nicely. He's not here to displace Ivanovic. But what he is here to do is shore up our RB options. Kane isn't ready yet, Hutch is unreliable due to his chronic injury problems and Ferreira is going next season. Good signing, at the right age aswell.
