The video of the fist goal on Google 365 and also in the one posted on here by Blackcowes shows that the referee does not signal a goal after MDM's effort crosses the line, he does not point to the centre circle and carries on watching play until Ottos shot enters the net when he immediately signals goal and points to the centre circle. The guy on the line carries on staring along the line after MDM's shot and makes no signal whatsoever.
UEFA are clearly telling porkies here. Really is a piss poor attempt at a cover up to protect themselves for not having goal line technology.
If Ottos shot had not gone in would they a day later have changed the score from 1-1 to 1-2? Obviously not.
