Sane, 23, left the Germany camp for the birth of his daughter, Rio Stella, last week and on Saturday made his first Premier League start of the season, taking just 97 seconds to open the scoring.
Raheem Sterling helped himself to a third goal this season as City made a similarly rapid start to the second period - Fulham's cavalier attacking approach leaving their excellent goalkeeper Marcus Bettinelli repeatedly exposed. Pep Guardiola had said his team would get fully up to speed after the global break and so they are.
"For City, two more seasons - what's left on my contract", Silva said in an interview for the Premier League Show.
City, whose 2016-17 revenue stood at £473.4m, have become only the second English club to break the £500m barrier after Manchester United in 2016 - a feat their neighbours repeated past year by bringing in £581.2m.
At blast of the whistle to make the end of the first stanza, Man City lead 2-0 going into the break.
Man City had other numerous chances to score, but could not convert the opportunities as the two Silvas David and Bernardo continued to pull the strings, for Etihad dwellers.
Fernandinho nearly got in on the act with a fiercely-struck shot which zipped inches past the post with Bettinelli beaten, and the Brazilian midfielder then combined with Sterling to set up Jesus, who again could not find the target. He said, "But we were aggressive when we had the ball and we created chances".
The buildup to the goal was a beauty mixed with a string of passes.
Fernandinho and Sterling also came close from long-range shots while the entire second half passed without Ederson being troubled in the home goal until injury-time when he dived to deny Aleksandar Mitrovic's shot.
The Cottagers were eventually put out of their misery, though, with the final scoreline flattering Slavisa Jokanovic's side on a day which saw them completely outclassed by the champions.
Since then the midfield playmaker has dazzled supporters at the Etihad Stadium with his incredible technical style, as well as being a pivotal part of three separate Premier League title triumphs.
