Timo Werner scored two first-half penalties as Chelsea maintained their unbeaten start in Champions League Group E with a 3-0 win over Rennes on Wednesday.
Frank Lampard’s side drew 0-0 with Valencia in their opening game before crushing Krasnodar 4-0 last week and got off to a fine start against their Ligue 1 opponents, with Werner slotting home from the spot in the 10th minute after he had been fouled by Dalbert.
The Brazilian was then dismissed after receiving a second yellow card for handball in the area four minutes before the interval, Werner stepping up to slam home his seventh goal of the season in all competitions.
Tammy Abraham added a third five minutes into the second half as Chelsea moved onto seven points at the summit of Group E, level with Sevilla.
Chelsea were given the opportunity to take an early lead when Dalbert tripped Werner in the penalty area, the German following up his penalty against Krasnodar last week with another successful spot-kick that proved too powerful for Alfred Gomis.
Dalbert’s dismal first half went from bad to worse shortly before the interval when he received a second booking for handling.
Abraham’s shot inside the penalty area, referee Felix Zwayer reaching the decision after consulting the pitchside monitor.
Werner stepped up again and lashed into the roof of Gomis’ net to double Chelsea’s advantage.
Hakim Ziyech blazed a half-volley over from eight yards shortly after the restart before Abraham turned home Reece James’ cross inside the six-yard area to put the Blues 3-0 up.
Gomis denied substitute Olivier Giroud late on as Chelsea ultimately failed to add further gloss to what was the most comfortable of victories.
