Has to be Stoke. This may sound like sour grapes but it honestly isn't. There are many teams in the Premier League thatplay the percentages game ie Villa, Blackburn, Bolton, Everton etc but Stoke beat the lot.
They play for every type of set piece available and even when their playmake goes off injured they have about 4 other players that are capable of launching throws in from 40 yards. I'd hate to watch that every week.
