The decisive moment came in the 18th minute.
Tactical Battle and Mourinho's Return
The game was a tight, tactical affair, with the scoreline reminiscent of a vintage Mourinho-era match. The visiting Benfica side, managed by the Portuguese legend, started brightly, forcing an early save from Chelsea goalkeeper Robert Sánchez when Dodi Lukébakio hit the post.
Moises Caicedo, in particular, was lauded for his commanding presence in the midfield, winning a high number of duels and tackles to break up Benfica's rare forward forays.
Late Drama with a Red Card
While Chelsea was able to see out the victory, the night ended on a sour note. Substitute João Pedro was sent off deep into stoppage time after receiving a second yellow card for a high boot.
Despite the late drama, the win provides a much-needed boost for Chelsea, who had struggled in their recent league fixtures. The three points put the Blues on the board in their Champions League group, giving them a solid platform ahead of the next round of matches.
Benfica, who were blunt in attack despite a few half-chances, have now lost their opening two Champions League games and face an uphill battle to progress. For José Mourinho, his first return to Stamford Bridge in nearly five years ended in quiet defeat against his former club.
