Ikero Casillas' joining of "Porto" certainly was not as successful as the player and his new team expected. "Porto" finished only third in the final tournament table, and the goalkeeper himself recorded the team's worst goalkeeping performance in the last 15 years. This season, "Porto" failed to achieve their goals not only in local competitions but also in European tournaments. In the Champions League, the Portuguese team finished third in the group stage and did not qualify for the knockout stages, dropping down to the Europa League where they stumbled at the first hurdle against "Borussia”. Casillas himself did not fare much better, conceding 28 goals in 32 matches this season. "Porto" had not conceded that many goals in a single season since the 2001-2002 season. In one game, the 34-year-old veteran conceded an average of 0.88 goals per match, while the previous season, Fabiano, who was the primary goalkeeper before Casillas arrived and became surplus to requirements, had a significantly better statistic of 0.41 goals per game. However, statistically speaking, this season was not the worst for Casillas. Representing the "Real" team, in one season he conceded more goals on average than in this season's "Primeira Liga" competitions. In the 2008-2009 season, he conceded 52 accurate opponents' shots in 38 matches. This season, the Spaniard could not avoid making mistakes either, and one of the most talked-about errors he committed in a match against "Braga":
