Indeed, but he is shirt number 18. If you take 18 away from 51 you get 33. Dan Burn is shirt number 33 but couldn't start due to an injury concern. His place was taken by Jakub Moder who wears number 15. If you take 15 away from 33 you get number 18 which, as we know, is Danny Welbeck's number. How freaky is that?
