Tennis

Tennis is a game played between two players (singles) or between two teams of two players (doubles). Each player uses a strung racquet to strike a hollow rubber ball covered with felt (most of the time yellow,[1] but can be any color or even two-tone) over a net into the opponent's court.
Tennis originated in the United Kingdom in the late 19th century as "lawn tennis" and had heavy connections to the ancient game of real tennis. After its creation, tennis spread throughout the upper-class English-speaking population before spreading around the world. Tennis is an Olympic sport and is played at all levels of society at all ages. The sport can be played by anyone who can hold a racket, including people in wheelchairs. In the United States, there is a collegiate circuit organized by the National Collegiate Athletics Association.
Except for the adoption of the tie-breaker in the 1970s, its rules have remained remarkably unchanged since the 1890s. A recent addition to tennis has been the adoption of "instant replay" technology coupled with a point challenge system which allows a player to challenge the official call of a point.
Along with its millions of players, millions of people world-wide follow tennis as a spectator sport, especially the four Grand Slam tournaments: Australian Open, French Open, Wimbledon, and the U.S. Open. The growth of tennis in Eastern Europe and the Far East has been especially notable in recent years.

Football

Football is the name given to a number of different team sports, all of which involve (to varying degrees) kicking a ball with the foot in an attempt to score a goal. The most popular of these sports world-wide is association football, also known as soccer and most commonly just football. The English language word "football" is also applied to gridiron football (which includes American football and Canadian football), Australian rules football, Gaelic football, rugby football (rugby league and rugby union), and related games. Each of these codes (specific sets of rules, or the games defined by them) is referred to as "football".

Sport in Oman

Oman national team;

Oman national team coach Julio Cesar Ribas is grooming 12 young footballers in an attempt to strengthen the national squad for the future assignments. The Uruguayan, who travelled across the Sultanate to watch Oman Football Association (OFA) league matches over the past few days, has picked 12 players — three new faces and the rest from the youth side — to train them ahead of Oman's 2010 World Cup qualifying game against Thailand. "After watching the league matches in different venues, coach Ribas has chosen 12 players. Three of these players are in the national reckoning for the first time and the others have played in the youth teams. Coach Ribas is training these players with an aim to include some of them in the national squad," said OFA General Secretary Taha al Khisry during the weekly media briefing here yesterday. "Ribas will put these players through rigorous training sessions for a three-week period before deciding on including some of them in the national squad," he added.
