On 19 September 2007, Barcelona beat Lyon 3-0 in the Champions League group stage. The match was notable for the appearance of substitute striker Bojan Krkić, who came on in the 88th minute for Lionel Messi to become the youngest Barça player ever to appear in the competition.
It was the second age barrier broken that week by Krkić. Three days earlier, at the age of 17 years and 19 days, he claimed a record previously held by Lionel Messi when he entered in the 78th minute against Osasuna, becoming the youngest Barcelona player to feature in a league match. He went on to make a total of 48 appearances for the club that season, as they finished the season without any silverware.
The club rectified that situation the following season, with Krkić making 42 appearances in all competitions and contributing 10 goals as Barça won a remarkable six trophies - La Liga, the Champions League, the Copa del Rey, the Supercopa del España, the UEFA Super Cup, and the FIFA Club World Cup.
