I agree with your last line there, but I am really paranoid about the lack of goals from the overall team in general. I know this is probably a bit of a silly reference, but if I am putting on an accumulator of two teams that have similar standings or form, I always look at their capability to score goals through the goals scored column. It often serves me well in the end.
I guess the point in general is that we need more goals in the team anyway, but I would be worried if we lost Gyokeres. That also being said, I still think he could do better, and I feel he has changed his style of play since he first joined a bit. He's a lot more selfish now, which is sometimes a good thing, sometimes frustrating.
