Mateo, his lungs burning, his legs heavy, gave chase. He sprinted back, his determination to atone for his error overriding his exhaustion. But he was too late. As Eden Hazard cut inside, Mateo lunged in with a desperate tackle.
He missed the ball and caught the Belgian on the ankle. The referee's whistle blew immediately, and a free-kick was awarded in a dangerous position, just outside the Dortmund penalty area.
Frank Lampard, the veteran English midfielder, stepped up to take it. His technique was perfect, the ball curling over the wall and into the top corner, leaving Weidenfeller with no chance. 2-0 to Chelsea. The Stamford Bridge crowd erupted, their roar a deafening celebration of a goal that had come completely against the run of play.
