Lewis impressive early strike set the tone for an opening half totally dominated by Guardiola’s side.
Indeed, for the first 10 minutes, Forest had only a handful of touches.
After 16 minutes, Omar Marmoush thrashed over when he might have hit the target, with defender Nico O’Reilly seeing his long-range shot going wide.
Forest ended a desperately bleak first half for them by failing to register a single shot, with City looking well on course to book their place in next month’s showpiece.
Forest needed a spark and manager Nuno Espirito Santo turned to Anthony Elanga – a surprise omission from his starting line-up – at the interval.
And the substitute had a golden chance to haul Forest level after just 57 seconds of his introduction.
Callum Hudson-Odoi’s pinpoint pass found Elanga unmarked, but the Sweden forward hit his shot wide of Stefan Ortega’s goal.
It proved to be a vital miss with City doubling their lead moments later.
Sels saved Matheus Nunes’ first shot with Kovacic’s follow-up striking Zach Abbott before a wrong-footed Sels reacted well to turn the ball round with his feet.

Surprisingly perhaps, VAR did not intervene, and referee Michael Oliver pointed for a City corner rather than to the spot.
City had every right to feel aggrieved but they need not have worried after Gvardiol outjumped Murillo from Marmoush’s corner to head home.
Marmoush nearly added a third shortly after the hour mark only to see his effort tipped over by Sels.
