An injury-time Olivier Giroud header rescued a 2-1 victory for Chelsea away at Rennes, to secure qualification to the knock-out stages of the Champions League.
Giroud nodded a spinning rebound past a number of defenders after a Timo Werner shot was blocked to remind Frank Lampard of his qualities, and restore a lead Chelsea had thrown away moments earlier.
Werner wasted a golden chance in the fourth minute, blazing over inside the six-yard box, as Chelsea started well.
Callum Hudson-Odoi made the most of his return to the line-up when he raced onto a beautiful cross-field ball from Mason Mount to slide the opener home in the 22nd minute.
Alfred Gomis clawed a Mount attempt off the line, before Rennes grew into the game and caused Chelsea problems.
An even second half sprung to life when ex-Rennes man Edouard Mendy tipped a Serhou Guirassy shot behind, then somehow kept a Gerzino Nyamsi header out from the resulting corner inside the final 20 minutes.
Guirassy punished Chelsea for not killing the game off, when his planted header from a corner saw them concede their first Champions League goal of the season in the 85th minute.
However, there was still time for substitute Giroud to secure the points late on.
Final Score – 1-2
