The referee came in for huge criticism after awarding one spot-kick and denying another in the first half at St James's Park, with some saying that he loves the spotlight too much
The 47-year-old punished the home team when he gave a debatable handball decision against a helpless Chancel Mbemba at St James's Park, from which Wayne Rooney opened the scoring, but sparked outrage just after the half-hour mark when he signaled to play on after Jesse Lingard appeared to have got nothing of the ball in a challenge on Daryl Janmaat in the area.
The decision bewildered and incensed Newcastle fans and neutrals who were watching along, prompting a gamut of reactions from fury to amusement on Twitter as his name rocketed up the site's worldwide trending list.
