England didn't really play impressively in their first match, despite getting the win, but they are still the favorites since that would be their opponent is Denmark who also didn't play well in the game against Slovenia. If England played with the strategy and composition of their players like they did against Serbia, then England would have a tough fight against Denmark. But if Southgate gives the stage to Cole Palmer and Anthony Gordon, I think it will increase their chances of winning.
The England team under the leadership of Southgate showed pragmatic and neat soccer in the previous match against the Serbs. I think that in the match against Denmark there will not be scored many goals. England is superior to Denmark on all lines and most likely the winner of the confrontation will be the English.
As I have said before, if England plays with the same strategy and composition of players as against Serbia, then they will not be able to have control over the course of the match due to the lack of creativity in their midfield. Playing Alexander-Arnold in defensive midfield is not effective, and I think that position is better filled by Kobbie Mainoo. Meanwhile, on the front line, I think the option to play Cole Palmer to replace Foden or Saka is also a good alternative because it could provide a new touch to England's attack line.
England cannot have possession of the ball this Euro and if Southgate won't change something , I'm afraid England won't have a long participation this time. Just look how nice and smooth Denmark is playing and their passes between players are so perfect that almost every chance they create is a chance to score a goal and England simply cannot catch the ball...
