Diego Pablo Simeone

Diego Pablo Simeone also known as “Cholo”. After starting his career with Vélez Sarsfield, Simeone moved to Italian Serie A club Pisa in 1990. The club was relegated in his first season and, after it failed to gain promotion the following year, Simeone was sold to Sevilla in the Spanish Primera División. Simeone played two seasons in Seville, after which he was signed by Atlético de Madrid. At Atlético, he was part of the team which won the double of the Liga title and Copa del Rey during the 1995–96 season.

In 1997, Simeone returned to Serie A with Internazionale and played two full seasons, winning the 1997–98 UEFA Cup in a side spearheaded by Ronaldo up front. In 1999, Simeone joined fellow Argentines Néstor Sensini, Matías Almeyda, Hernán Crespo and Juan Sebastián Verón at Sven Göran Eriksson's Lazio. The side had gone close to the Scudetto in the season before Simeone's arrival and he helped deliver the championship after a season where Juventus led the standings by two points going into the last day. After winning the double in Spain he would then add the Italian double as Lazio edged out Inter to claim the 1999–2000 Coppa Italia. Simeone ended his playing career for Racing, playing his last match, and then became manager for the same team. After a rough start, the team made an impressive finish in the 2006 Clausura. When ownership of the club changed hands, Simeone left Racing in May 2006.

On 18 May, he became head coach of Estudiantes de La Plata and soon led them to their first league title in 23 years after defeating Boca Juniors 2–1 in a final match. In an October 2006 poll in the sports daily Ole, Simeone was voted as the best manager in the Argentine league. He was also praised as a "born manager" by former Argentine international Roberto Perfumo. Simeone left Estudiantes after the end of the 2007 Apertura, where Estudiantes was not a contender after a bad start, but had a strong finish of nine games without defeat. On 15 December 2007, Simeone was unveiled as the new River Plate coach. The contract was reported to be a yearlong. After an early elimination in the Copa Libertadores losing to San Lorenzo in the second round, Simeone and River Plate went on to win the 2008 Clausura championship after beating Olimpo 2–1 in the Monumental.

Simeone announced his resignation as coach of River Plate after their elimination at the quarter-final stage of Copa Sudamericana by the Mexican team Chivas and a poor run of form of 11 domestic games without a win which left them bottom of the Primera División Argentina with only six games remaining. Simeone joined San Lorenzo, following the club's exit in the first round of Copa Libertadores 2009. The coach quit San Lorenzo due to poor results and mounting criticism.

Simeone flew to Sicily to join Serie A side, he left his post after helping Catania stave off relegation. Simeone was named as the new coach of Racing Club for a second spell in charge. On 23 December 2011, Simeone was unveiled as the new Atlético Madrid coach. Simeone won the UEFA Europa League with Atlético beating Athletic Bilbao 3–0. He went on to win UEFA Super Cup with the same team beating Chelsea 4–1, earning his first two European trophies. He won the Copa del Rey with Atlético beating Real Madrid 2–1. Simeone led the team to a third place finish in 2012–13 La Liga, the club's best finish in the competition since 1996.
