I am going to share knowledge about two running international tournaments, Copa America and Uefa Euro.
The Copa América Centenario is an international men’s association football tournament being held in the United States in 2016. The competition is a celebration of the centenary of CONMEBOL and the Copa América, and is the first Copa América hosted outside of South America.
The tournament is the 45th edition of Copa América since its inception in 1916. It is being held as part of an agreement between CONMEBOL (the South American football confederation) and CONCACAF (the football confederation for North and Central America and the Caribbean) as a special edition between the usual four-year cycle, and features an expanded field of 16 teams (an increase from the usual 12), with all ten teams from CONMEBOL and six teams from CONCACAF. The winner of this tournament will not receive an invitation to the 2017 FIFA Confederations Cup, as Chile has already qualified by winning the 2015 Copa América.
The 2016 UEFA European Championship, commonly referred to as UEFA Euro 2016 or simply Euro 2016, will be the 15th edition of the UEFA European Championship, the quadrennial international men’s football championship of Europe organized by UEFA. It is scheduled to be held in France from 10 June to 10 July 2016. Spain are two-time defending champions.
For the first time, the European Championship final tournament will be contested by 24 teams, having been expanded from the 16-team format used since 1996. Under this new format, the finalists will contest a group stage consisting of six groups of four teams, followed by a knockout stage including three rounds and the final. 19 teams (the top two from each of the nine qualifying groups and the best third-placed team) joined France who qualified automatically as hosts; a series of two-legged play-off ties between the remaining third-placed teams in November 2015 decided the last four spots at the final tournament.The winning team earns the right to compete at the 2017 FIFA Confederations Cup hosted by Russia.
