Even if we agree that he was offside (and I genuinely didn't see if he was or not from the briefest of replays once UEFA made their minds up 5 minutes later that it was offside) - the ref signalled for a foul, so mechanically the goal was wrongly disallowed.
In that it was disallowed in an incorrect way. Which is pretty piss poor officiating.
