Yes, it is difficult to work out how much is luck and how much is skill.
I did notice today that so many of the long balls just fell kindly for us as well as the parts of the match where the ball was hit randomly by both teams.
But the problem with luck is that it evens itself out in the end. I remember that in one of the last 3 years we were very lucky for a period and then it all went to pot.
Talking about luck, I thought that Cole Palmer was going to be back for our game but it looks like he won't be. I think that the last time he played against us was when he was with City and he scored against us. I don't think that we ever played him since he joined Chelsea as he has always been injured.
