Arsenal were undefeated in the league, claiming the title. Having previously been a striker or attacking midfielder, he made a reputation for himself as being an attacking defender, although he only scored one goal and had one assist. Touré was in and out of the Arsenal team during the 2004–05 season, battling for a first team place with the likes of Philippe Senderos and Pascal Cygan to play alongside Sol Campbell in defence. Touré ended the season with a FA Cup winners medal playing 50 times for Arsenal that season and scoring one goal.
