Iván Álvarez (born 20 January 1980 in Curicó) is a Chilean football forward. He currently plays for Rangers de Talca. He is the twin brother of Cristián Álvarez. Forwards, also known as strikers, are the players on a team in association football who play nearest to the opposing team's goal, and are therefore principally responsible for scoring goals. This very advanced position and its limited defensive responsibilities mean forwards normally score more goals than other players; accordingly, they are often among the best-known and most expensive players in their teams. This is one of modern football's most demanding positions; it requires intelligence and speed, both of execution and of thought, to perform the role well.
