Of course you're painting over the fact that he's trying players out to see how they perform certain roles. Folly?
It was our first preseason game, where afterwards Ange even said they'd only been working on their attacking play.
You're evidently unfamiliar with how AP sets his team's to play. When we're attacking, he wants their box overloaded. Christ, he even had his CB's attacking the box with Celtic alone.
Football is far more fluid than the rigid formations you seem to think players are only suitable for. When we're attacking, if you play in midfield you are an attacker in AP's system. We're playing a high line, so unless you're sitting level with our defenders, you're in a position to attack. You are expected to recognise the opportunity and act on it. If Skipp is in or around their penalty box, it's because he's seeing an opportunity to attack. Couldn't give a shit what his 'perceived' technical skills are, they're more than good enough to capitalise on an attacking opportunity.
