23-year-old summer signing Andre Schurrle scored the home side’s opener on 32 minutes before substitute Demba Ba scored the goal that sees them through to the semifinals of the competition in the 87th minute of the game.
The Germany international has now explained precisely how Portuguese coach Mourinho set out to win the tie and what he demanded from his team.
"He played a big role. We had many meetings. He knew the situation. He gave us advice," he said.
The 51-year-old Chelsea coach knows a thing or two about how to approach high profile opposition in the Champions League having won the competition twice with FC Porto and later Inter Milan and it seems his invaluable experience paid off on the night.
"Before the game, we said that we had to play like we always do. A little bit more risk, maybe, because we needed to score,” Schurrle added.
Chelsea’s strikers, specifically Fernando Torres, came under fire from critics in the aftermath of the first leg for their complete lack of threat in front of goal but, it appears the Special One’s instruction to play with more risk may well have given Schurrle and Ba, at least, the confidence to break the deadlock.
"But the boss said that we needed to be patient because we could score at any time. We wanted to score in the first half because then we had all the options. But after that we needed patience, because everybody wanted to go, go, go,” he continued.
"The manager said it didn't matter if we scored in the 46th minute or the 90th minute. And that's what we did.”
Indeed they did and, as they say, the rest is history – PSG were head and shoulders above the Blues in the first leg at the Parc des Princes but the Ligue 1 champions and last season’s quarter-finalists failed to take the same game to Chelsea at the Bridge.
