I haven't quoted 'some strange stats'. I've quoted possession, shots and score. They're not strange, they're fairly straight forward, but of little significance. Based on that possession and shots, without knowing the result, you'd have logically expected something like 3-1, 2-1, 4-2 (i.e. a win by the home side, with the away side scoring at least 1 of their 15 shots and from 42% possession).
Chelsea weren't that clinical. 31 shots, scored 8. Could easily have had more (I watched it). And a couple of cracking finishes where the beloved XG would have been 'this is hard to score' I would imagine. It really doesn't matter - said cracking strikes hit the bar or misses by an inch = a miss. Said cracking strikes half an inch inside the goal = a goal. Such small margins. Much easier chances (better XG) went begging.
There's only one stat that matters. I couldn't care less what our XG's or whatever are. I really don't want to hear that we're doing ok because our possession is high or our XG conversion is whatever. It really doesn't matter, even more so as a pattern.
