Zappacosta only did well due to the amount of space he was given. Atletico didn't view him as a threat and nor should they, as they as well as the 40,000 in attendance and millions of viewers knew what he was going to do, cut inside.
I know we created a shit ton of chances last night, but this is why I stress the importance of having quality wing backs in our system. Moses tore Atletico's back line a new arse, but his delivery in the final third was appalling. Zappacosta had literally the freedom to do whatever he'd please, yet still wasn't a threat given that he has no pace and he will never take a defender on and whip in a ball.
