Harry Kane has found his rhythm again this season that 12 goals was belongs to him at premier league from 15 matches this indicated there is good opportunities to Kane will continue his achievement because he is England captain and always be playing regular and as top scores status on world cup 2018 he will counted as one of the players who scoring more goals for England for the current world cup and actually if we talking about England they are is not in the good shape because on Nation League this team has been relegated and from this tournament Southgate have to proven he can improved England performance moreover England at group B with Iran, United States and Wales which is on the paper England as the strong candidate qualified to the next round
Haaland changed the idea of "good number of goals to score so far" that when I see him at 18-20 goals or something, and even more when you consider totals, Kane didn't even look that great to me, it looked like he was having a bad season and thats it, nothing more.
In reality he is of course good, and I am sure he would be good for England as well, he is a good player and he will continue to be a good player for a long time and will help them during world cup as well. They do have great scorers on wings and midfield as well so it will not be only Kanes issue to score, he will get a lot of help from other positions when the team needs a goal as well so passing is very important too.
