Whenever Barça have drawn the first leg of a Champions League tie under Pep Guardiola, they have eventually qualified for the next round.
In four years on the first team bench, the FCB manager has qualified 25 out of 27 attempts in knockout matches.
Guardiola’s Barça has drawn four Champions League first legs, and the players have always responded by eventually sealing qualification. The first case was in 2008/09 when a 1-1 draw away to Olympique Lyon was followed by a convincing 5-2 victory at the Camp Nou. Later in the same competition came one of the most memorable moments of the Guardiola era. Barça and Chelsea met at Stamford Bridge to battle for a ticket to Rome after the game at the Camp Nou had ended scoreless. An Andrés Iniesta strike in the very last instant was enough to secure a 1-1 draw and qualification for the final by virtue of the away goals rule.
The next season, Barça also drew two first legs but went on to qualify. In the first knockout round they crossed paths with Stuttgart and drew 1-1 away before cruising into the quarter finals with a 4-0 win at the Camp Nou. In the following round they met Arsenal and drew 2-2 at the Emirates before a magnificent Leo Messi scored all four goals in a 4-1 win at the Camp Nou that ensured passage into the semis.
