But most of the teams you mentioned didn’t make it to the latter stages; they were beaten by a better side, at least on the day.
As with any competition, if England are ultimately triumphant, there won’t be any caveats saying, "England won the World Cup, but they didn’t play Germany, Brazil or Argentina on the way". It will simply say "2018 World Cup Winners England".
Like others, I was unsure about Southgate when he was appointed, but he has done a great job and has stuck to his guns with both his system and personnel.
This is still a very young team and Southgate should be allowed to develop it and bring in new faces as and when needed.
