Events in recent weeks in European football have raised the lingering question regarding the aptitude of referees for officiating in the more high profile matches. In Bundesliga at Hoffenheim, there was the so-called 'ghost goal' and in the Premier League more recently, two match results were partially influenced by contentious decisions by the officials. Although, referees are now professional and are required to meet set standards before being considered suitable for purpose, it could be argued that there are insufficient streetwise ex-footballers employed in the role.
