Unless you are playing against a significantly better football team why set up to defend?
Of course you defend as well as you can when you have to but to do it by choice seems bizarre to me. Southgate is by nature very cautious and I called it on here before the Euros.
I still believe we had the most talented squad in the competition particularly in attack. Must be a thing with ex Middlesbrough players to try and defend your way to a 1-0 win despite it rarely working.
