It seems that Southgate decided to stick to his plan to score first and then play cautiously, defensively, but now I think his plan started to fail, because for the first time Serbia started to have some moments that can be called at least a little dangerous. Of course, I want England to play attacking soccer, but for Southgate the result is probably more important than a beautiful game.
Nevertheless, Serbia still have chances, because one goal can always be scored, but if England score the second goal, they will probably win the match with 99% probability.
