On the other hand, I'm pretty sure England can qualify as group winners easily, but their next journey will not be easy. Of course they have good squad depth in almost every line, but Southgate must find a strategy to win the match easily. Next England will face Denmark, they have to do it in a better way.
One goal may have been enough to defeat Serbia, but one goal may not be enough to defeat Denmark. I expected more goals from England, and I must say that the one goal in their first game is disappointing but a progress from their last friendly game where they lost. The performance of England has to improve, the competition will be tougher and if they will win this competition, one goal will not be enough against the big teams. England should be scoring as many goals as Spain and Germany.
Actually, England didn't play as well as I expected in that match. And yes, England must be able to increase the effectiveness of their front line again. Because they still have difficulty creating good opportunities in this match. but this also happens because Serbia actually also has quite good squad depth. So I wouldn't be that surprised if Serbia could almost match the English National Team's game. And the English national team was lucky because the Slovenia vs Denmark match only ended in a draw. This automatically puts the English national team in first place in Group C.
But apart from all that, I am also quite confident that England will indeed qualify from the group stage and will even continue to be in first place in Group C. Against Denmark it might be more difficult but I am sure the English national team will still be able to win it.
