The 2009-10 campaign delivered a competitive, yet transitional season for Lyon as Les Gones finished a strong 2nd in Ligue 1, officially ending their historic run of seven consecutive championship titles. The season was defined by a thrilling run to the UEFA Champions League semi-finals, their best-ever performance in the competition, which captured the imagination of the fans. Spearheading the attack was the prolific Argentine forward Lisandro López, whose 15 league goals proved decisive in a campaign built on an exciting blend of star power and new faces. It was a fiercely contested year that marked a significant change in the club's domestic fortunes but remains an unforgettable chapter for the club's European exploits.
