Here's how Villa alone up top can work because the other midfielders are now attack minded:
I'm going to be kind of lazy and let the gif speak for itself. But it shows early how Orlando's defense collapses three guys on Villa, which allows Poku to dribble forward into the space, and Calle to run unmarked. As a result, Villa steps back and receives the ball with space, makes one guy miss and then buries it.
Sure enough, on our next goal, same thing happens. This time Poku hits the wide open running midfielder rather than Villa to his right:
I'm thinking Villa *can* play up top by himself, provided he's not *isolated*. Him drawing 2-3 defenders every play should be a positive, not a negative.
Probably the best post I've ever seen on here.
