as you can get with Sweden already out having lost to both Ukraine and England and France in good form (I know they said they want to end on a high note, but so did the Irish and look what happened).
Rooney is back for England. They will be motivated to try and win the group (trailing by one in goal difference). 'Nuff said.
All in all, worst that can happen is one of these teams draws. Chances of an outright loss is pretty damn low. At the end of the day, we're looking at two superior teams vs two inferior teams. Wouldn't be surprised if both win by more than one goal. Don't overthink it guys.
