Cancelo's equaliser in Istanbul was legitimate. Everyone screaming offside should take it up with the law, because the officials got this one right.
In the 43rd minute, with Galatasaray up a goal in their own stadium, Dani Olmo threaded a pass toward Anthony Gordon. Gordon was in an offside position. He left the ball alone, let it run past him, and Joao Cancelo arrived from an onside spot to finish across the goalkeeper. 1-1.
It's the offside law working exactly as written. A player in an offside position has done nothing wrong until he touches the ball, blocks a defender's sight of it, or challenges for it. Gordon did none of those things. He stepped out of the picture and let a teammate who was legally onside do the damage. The smart, legal move. If you want to hand out credit, give it to Gordon's reading of the situation and to the referee and VAR for making the correct call.
The obvious objection: maybe Gordon just got away with a missed flag, and people invented the cleverness story afterward to excuse an official's mistake. Watch what actually happened to the ball. If Gordon had touched it, obstructed a defender, or contested it, that's an infringement and the goal dies. What happened was the opposite. He let it travel untouched. You don't even need intent for a defense here. The ball ran clean through, untouched, to an onside Cancelo.
The officials do deserve criticism for the silence. There was no clear on-screen explanation at the time, and that's how a correct decision gets recast as a robbery in a hostile away end. Fix the communication and half this argument never starts.
Muddying things further, Galatasaray had their own goal wiped out minutes earlier. In the 34th minute Victor Osimhen met a corner, Baris Alper Yilmaz got a touch on the way in, and VAR ruled it out for offside. Two offside-adjacent moments in the same half and same crowd, one goal stood and one didn't. You can see why "inconsistent" trended, but it isn't. Those are different sub-rules. Yilmaz was offside at the moment the ball reached him and interfered with it. Gordon was offside and then refused to interfere. One is an offence, the other is a player doing the one thing the law lets him do. Calling that a double standard misreads the rulebook; two different rules were at play.
There's a separate complaint worth addressing: Lamine Yamal went down appealing for a foul just before the goal, and play carried on. Referees wave those away constantly when the ball breaks loose, and this one broke loose to Olmo, then to Cancelo. Live with it.
Barcelona went on to win 4-1, so the equaliser stopped being the story anyway. But on the one call people are still relitigating, Galatasaray are owed sympathy for the atmosphere they built and nothing for the complaint itself. Gordon played it perfectly. Galatasaray got outsmarted, plain and simple.
