The 2004/2005 Premier League season is memorable for Chelsea FC's outstanding defensive record, which played a crucial role in their successful campaign under manager José Mourinho. Chelsea conceded only 15 goals during the entire league season, setting a new Premier League record for the fewest goals conceded in a single season at that time. This defensive prowess was a key factor in Chelsea winning their first Premier League title in 50 years.
Under Mourinho's tactical guidance, Chelsea adopted a disciplined and organized defensive approach that focused on solidifying their backline. The team often played with a compact defensive shape and relied on a strong defensive midfield presence to protect the defense. This approach not only limited the opposition's goal-scoring opportunities but also allowed Chelsea to control matches and counter-attack effectively.
