Silva featured in all but one league game last season, yet has struggled to find that game time at City - starting just three times in the Premier League.
After late victories against Huddersfield Town and Southampton, Silva scored with seven minutes on the clock for a City side who, in cantering to an eight-point lead, are showing all the hallmarks of champions-elect.
It was City's first competitive loss since being beaten by Arsenal in an FA Cup semifinal in April. "That gives us the best chance to win".
While Benjamin Mendy waltzed into the first-team picture on account of little competition - prior to injury - Bernardo has found his route to the pitch blocked by the likes of Sane, Kevin de Bruyne, Raheem Sterling and namesake David Silva.
Madrid finished the 2011-12 season as champions and Guardiola, worn out by the constant sniping, stepped down at Camp Nou and would not resurface at Bayern Munich for another year.
"But today, since after five minutes in the second half, I felt we were going to score". I thought most of it was outside the box.
Seven months on City look nearly transcendent, their sublime and devastatingly effective possession football reminiscent of Guardiola's great Barcelona team. "They wouldn't come out for the game, they came for the counterattack only".
The Italians must also make sure they beat Group F basement boys Feyenoord, who have nothing left to play for, but showed against City at the Etihad recently that they can be challenging opponents.
United are just eight points behind City, but Pep Guardiola's side are now enjoying an extended unbeaten run - having won their last 13 games.
Angelo Ogbonna's opener for West Ham came directly from a corner, as did the goal that City conceded against Huddersfield last week, while Southampton troubled them from set pieces during the week.
"We have played against some wonderful teams this season, Chelsea, Liverpool and Arsenal and we did well". Chelsea have a big squad that can stand up to every game, so I hope they can go through December in a good way.
