José Mourinho’s highly-anticipated return to Stamford Bridge as Benfica manager ended in frustration on Tuesday night, as the Lisbon side fell 1-0 to Chelsea in Champions League match day two action in London.

Sections of the home crowd at Stamford Bridge warmly greeted Mourinho before kickoff. On the pitch, however, it was a tense tactical affair between two sides looking to rebound from opening defeats in Europe.

The only goal arrived in the 18th minute, when a low cross from Chelsea’s Alejandro Garnacho, following a build-up started by Pedro Neto, deflected off Ríos and into his own net.

Benfica pressed for an equalizer, with attempts from Fredrik Aursnes and Georgiy Sudakov among those that tested Chelsea, but none broke the deadlock.

Despite the defeat, Mourinho praised his players’ resilience.

“We came to Stamford Bridge, against a strong Chelsea, and showed personality,” he said post-match. “It’s painful to lose in this way, but I saw a team fighting until the last second. This is the mentality we must keep.”
