Partnering Colombian international and fellow newcomer Luis Amaranto Perea in central defence, Pablo contributed to Atlético achieving the third best defensive record in the 2004–05 La Liga season; only Barcelona and Real Madrid conceded fewer goals. The team finished in a mid-table 11th position because they did not score enough, as illustrated by Pablo's three goals making him their third best league scorer. His performances earned him selection for the senior national team, in a friendly against England in November, and reported interest from major clubs. Both he and Perea were given a pay rise and a contract extension until 2009. In 2005–06, Pablo was a fixture for both club and country. He and Perea repeated their efforts of the previous season as Atlético finished in 10th place with the fourth best defensive record, and he partnered Carles Puyol at the 2006 World Cup.
