i can see why Tainio left Villar. He was very close to the ball and almost made a turn over. Miller should of ran back quicker. he sort of gave up on the play and expected tanio to make the turnover. 9/10 times that might be true but Miller should of ran back.
To be honest he was pretty far up field when the play broke the other direction so I don't know if he could have done anything, but I've noticed that Miller is often very lazy when it comes to moving back into his defensive position, even at times where the other team is breaking down his side.
