Walter Adrian Samuel (born March 23, 1978 in Laborde, Cordoba Province) is an Argentine football (soccer) player who currently plays for Internazionale of the Italian league, and for the Argentine national team.
Samuel started playing professionally in 1996 in Argentina for Newell's Old Boys, and a year later moved to Boca Juniors where he stayed until 2000. In that year AS Roma bought his pass for 22,250,000 US Dollars. He gained notoriety as one of the best defense players of the Italian league, which attracted interest from Spanish team Real Madrid. Real paid 25,000,000 Euros (almost 30,000,000 US Dollars) for his transfer in 2004. But Samuel had a poor performance that season, and in August 2005 he returned to the Italian League, with a transfer to Internazionale for 16 million Euros, and a 4-year-contract of 4.8 million US Dollars per year.
The centre-back got the nickname of Il Muro (The Wall) while playing for AS Roma in Italy, due to his defensive skills.
He played 45 matches for the Argentine national team, scoring 4 goals. He played for his country in the 2002 World Cup.
