Did Sweden look like group winners to you ? Did Colombia ?
They also lost to group leaders, who went on to beat the group leaders of group whatever-it-was, Brazil. Now that deserves plaudits. England have got lucky.
You are right though in saying that Germany, Argentina and Spain were , for whatever reason, totally underwhelming. I still think any on of those sides could and probably would beat england in a quarter or semi.
So, ye. They can be "world-cup finalists" england or even "2018 world cup winners" england, it still won't make them the best team in the world. Far from it.
