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.
Howard Webb says yes it should be a penalty but defender gets bit of ball just after making the challenge and difficult for ref to tell.

Most people weren't as balanced.
No luck of the Irish so far especially with that blatant penalty. Game needs a goal and the ref to step up and do his job. #ITAIRL

If that's not a penalty then penalties don't exist.

Ogbonna could choke slam Shane Long through the goalpost and this referee wouldn't give a penalty. Shambles

FIFA RULE 28.1b
An Irish player must receive a fatal injury in the box before a penalty is awarded.#IREvITA

This ref in the Irelabd game must be getting paid off by Italy....clear penalty there!

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.
