I wouldn't worry too much about what happens when England play anybody half decent.England made a bunch of mistakes at the back and Pickford just pumps the ball upfield when under the slightest pressure, that was not defensively astute. The only thing which prevented an, at best very average Serbian team, scoring was their woeful ability in the final third. Anyone half decent and England would have been taken apart last night. I know you can only beat what’s put in front of you but England hardly put down a marker for the tournament like some other nations have. In fact I’d actually say the exact opposite, they gave Denmark and Slovenia hope. Thankfully, due to this new crap format, you probably only need one win to go through.
I don't think I can remember us playing a single team who haven't suddenly become "very average" the moment England come to play against them.
