Euro 2016: Ireland fans are incensed by what looked like a stonewall penalty against Italy
For much of the first-half against Italy it seemed that the Irish players had swapped shirts with the Azurri, such was the dominance of their play.
Jeff Hendrick came close with a long-range effort, Salvatore Sirigu was being troubled from Irish corners, and the Italian full-backs had their work cut out.
Late in the half James McClean burst into the box only to be brought down as he was about to shoot. At least, that's what it looked like to most people. Unfortunately for Ireland, the one person who didn't agree was the only one who mattered - the referee.
Former Premier League ref Howard Webb agreed with the incensed fans, but also had his referees' union hat on.
Most people weren't as balanced.
While some just kept it simple.
That Thierry Henry incident was inevitably brought up.
And to make matters worse for Ireland, Shane Long had previously been hit in the face at a corner - an incident which the referee blew for but, rather than giving a foul, asked for the corner to be retaken.
Italy had been repeatedly handsy in the box.
Only one thing is certain. The referee should definitely steer clear of Roy Keane for the foreseeable future.
