totally disagree, if they can tell someone is an inch offside then to then not give it would be ludicrous for me. Went against us this time, but taking that away from the discussion it was the right call... Close but the right call
As is your right but then we need VAR to spot every single thing on the pitch at all times to get the correct calls 100% right 100% of the time.
An inch offside still falls under the advantage to the attacking team for me, it still marginal and still on perceived pictures shown only after the event and if it is taking a guy in a TV room 3 minuted to decide then it is really to close to call, again in my opinion.
There are still compelling footage hinting that Aguero wasn't offside because of the speed he was moving back to get onside and then the ball going the opposite way, of course it is tough shit as it was disallowed but decisions that are that close are not what it is about for me.
Think the 3 yard offside Liverpool got earlier in the season or the Spurs two v us a season or two back, they were disgraceful decisions.
