One of the recipes of a football game is a trusted referee. They are the ones who will take care of implementing the pros and cons, the do's and don'ts of the match. They are the walking, or should I say - the running rules and regulations in the playground.

The 20^th FIFA World Cup is now on the climax part of the season as the quarter finals is about to begin. The round of 16 matches will be a surely tough fight for the qualified teams. For the matches 49 and 50, in which four teams from South America will battle up in the first of the so-called Round of 16 matches, the FIFA has already announced the official referees.

For the face-off of team Brazil and team Chile, England's Howard Webb will officiate the match that will be held in Belo Horizante. Mr. Webb is a 42-year-old referee that is a sure familiar face from the two teams. At the 2010 FIFA World Cup, Mr. Webb oversaw the encounter of the 3-0 win of Brazil over Chile, also in the Round of 16. Howard Webb has remarkable highlights in his career, such as the two FIFA Confederation Cup (2009 and 2013), two European Championships (2008 and 2012) and the 2012 UEFA Champions League Find.

On the other hand, the battle between Colombia and Uruguay will be handled by a 41-year-old Dutch, Björn Kuipers.
