Manchester City and Leicester City shared a set of offside goals. Fernandinho having a rocket from 30 yards ruled out in the opening stages before Jamie Vardy rounded Ederson and strolled the ball into an empty net in the final moments of the first half, but both players looked over to see the flag raised.
Benjamin Mendy opened the scoring, curling a tracer dart into the bottom corner after dummying past the onrushing Marc Albrighton.
The Foxes were chasing the game now, with Ricardo Pereira and James Maddison being brought on to get something from the game. However, this inevitably left gaps in the Leicester defence, and who else but De Bruyne found them?
A pinpoint through-ball found Gabriel Jesus in acres of space, who played a one-two with Raheem Sterling and then poked home to give Man City some breathing space.
Sergio Agüero and Jesus in the Starting XI - an unusual sight for City fans.
Since joining in 2017, Jesus has only played alongside Agüero on 19 occasions. In those 19 games, the pair have mustered up 56 goals, leading the side to victory in 17 of those 19 games, while also keeping City from recording a loss.
With the Argentine striker all but confirmed to leave at the season, Jesus is taking his opportunity to learn from a true great of the footballing world.
Despite Agüero being subbed off at this point, it is not a coincidence that Jesus was in the right place at the right time to slot away City's second goal against a pressing Leicester side.
Another important duo on Saturday evening, was defensive midfield partners, Fernandinho and Rodri. Both worked tirelessly throughout the game, with Rodri given a slightly unconventional 'box-to-box' roll (or box-to-boxdri as some City fans called it).
Although it may have gone unnoticed to some, the pair kept the Leicester's biggest attacking threat quiet all game, Vardy. The English talisman gave City a scare on the stroke of half-time, but was ruled offside imminently.
Other than that moment, the two were in sync and were the main reason for City's total domination for large parts of the top-four clash.
It has been a tough season for Benjamin Mendy, to say the least.
Despite being on the City bench for 16 games, Mendy has only been substituted on once, coming on against Southampton for a total of nine minutes.
Mendy took the opportunity on Saturday to prove exactly what he is capable of, with a stunning strike to give City the lead, alongside a clean sheet.
It seemed that there could be some unrest or something going on behind closed doors, but it is clear that Mendy's love for the club is still blossoming.
Do Citizens see Mendy in the club's future? Or will Pep Guardiola look to bring in reinforcements as the side continue to develop while the Frenchman sits on the bench for the majority of the season?
Man of the Match performance
After starring for Belgium over the international break, a rest for De Bruyne would have been more than deserved. However, the superstar's name is always the first on the team sheet.
De Bruyne showed flair, aggression, passion, that has been missing recently. Despite always bringing his fancy passes and game-winning moments, the game against Leicester had triggered something in the world-class midfielder - the dirty side to his game that is not always evident.
Despite not recording a goal or assist himself, he played a huge role throughout the game and played a beautiful through-ball to Jesus, who eventually finished off a flowing City goal.
De Bruyne was inches from opening the scoring with a freekick which cracked the crossbar, leaving the woodwork (and Kasper Schmeicel) shaking.
The Man of the Match winner had this to say about the game: "The first half we totally dominated. They had the once chance from Vardy but it was offside. It was basically one team playing,"
"Second half Leicester did a little bit better but I think if you look at the 90 minutes, and it was 2-0, we deserved even more goals," De Bruyne told Sky Sports.
Remembering a Leicester City legend
A moment of respect before the game took place to remember the life of Frank Worthington, ex-Leicester City striker.
Applause rang out around the King Power stadium before kick-off.
The 72-year-old passed away on 23 March, during the international break, following a long battle with illness.
Touching tributes flooded in all over social media, with the likes of Gary Lineker paying his respects to a footballing great:
Worthington played in 22 consecutive Football League seasons from 1966, scoring 266 goals in 882 appearances in all competitions.
In 14 of those campaigns he played in the top division, notching 150 goals in 466 matches, and won the Golden Boot award in 1978-79 as the leading scorer ahead of Kenny Dalglish and Frank Stapleton.
