From the clips I’ve seen I think he probably was offside. What upsets me more though is the penalty we should have had when Pinnock nearly had the shirt ripped off his back, I can understand the ref not giving it though it was pretty crowded to get a good view of it.
This is where live TV coverage evidence sucks, it can show a clear evidence of a penalty and you get sod all but they show dangerous play and days later a player gets a 3 match ban.
