Scottish referee makes an injury-time howler in Europa League clash
Willie Collum has found himself as public enemy No.1 among the Roma faithful after a late penalty decision denied the Italians of all three points in the Europa League.
The Scottish referee adjudged Chris Smalling to have blocked a late shot with his hand, though replays showed it hit him in the face.
Smalling and his team-mates were aghast at the decision and had to watch on as Lars Stindl levelled in the match in the 95th minute.
