Didier Drogba has revealed how Portuguese defender Jose Bosingwa was the mastermind of the club's famous 2012 Champions League win.
In the crucial semi-final second leg against the all-conquering Barcelona, Roberto Di Matteo's Blues were hanging on.
Gary Cahill had been subbed off after just 12 minutes with a hamstring injury - replaced by the Portuguese right-back - David Luiz wasn't in the matchday squad and then John Terry was sent off for a kneeing Alexis Sanchez.
With 45 minutes to play and a goal down in the Nou Camp, one more goal for the home side would have been the end of Chelsea's hopes.
But Bosingwa had other ideas, reveals Drogba in his autobiography, Commitment, which is released this week.
"The players really stepped up to take responsibility," Drogba writes.
"The manager was telling Branislav Ivanovic to play centre back but Jose Bosingwa said, 'No, no, I will play centre back', and carried on to say where he thought others should play.
"'I don't care', I remember saying. 'I can play left back if necessary. We don't need a striker. I'll play striker and left back, whatever it takes'."
With 10 men behind the ball for almost all of the second half Chelsea were able to hang on, before Fernando Torres scored that late goal to seal Chelsea's place in the final.
The Ivorian striker, who won four Premier League titles and eight other major trophies in two spells at the club, went on to score the equaliser and then the decisive penalty as Chelsea shocked Bayern Munich in their home stadium in the final.
