Chelsea certainly had the rub of the grain last night from referee Felix Zwayer, with more than one dubious decision going their way. But their night had not got off to the best of starts, when German forward Kai Havertz tested positive for COVID and had to drop out of the squad. He now has to self isolate for ten days.
Chelsea manager Frank Lampard nevertheless named a strong side, with Werner, Abraham and Halim Ziyech in attack.
Ziyech’s early flick went narrowly over the bar as Chelsea pressed – but then Dalbert brought down Werner as the German darted into the area. There was no doubt about that spot kick.
After that, Rennes, lying third in Ligue 1, caused Chelsea real problems with their swift passing – and goalkeeper Edouard Mendy, playing against the club he left in the summer, had some anxious moments.
When Ziyech gave away a free kick on the edge of the area, Benjamin Bourigeaud curled in a wicked free kick that fizzed only an inch past the far post.
Then though came the second penalty, five minutes before half time, as the hapless Dalbert was again the fall guy – and again Werner was ruthless.
