Saw that stat earlier, certainly did not feel like they had more of the ball. They must have counted the 8 minutes or so when their player was down and they were passing a ball around.
I'm sure I read on here that possession is measured by how many passes are made by each team rather than time in possession of the ball, which seems a weird metric. So I wouldn't say it's massively indicative of actual possession of the ball, it just means we made less passes in our possession.
Yeah I read that too, but when I've checked it on Flashscores during a game it didn't seem to match up.
From Flashscores now, total passes 827, 322 is 39% of that.
Weird, maybe when it's live the data comes through at different rates.

It seems to be done on total passes rather than completed passes, don't ask me why. It's definitely done that way though, a guy from Opta was on the Totally Football Show.
