That's because Norwich made just one effort all game, and that flew harmlessly wide off target. Kyle Walker - 7/10With the Canaries almost never venturing forward, Waker stationed himself high up and looked to work a few openings for Manchester City. His passing was exceptional (96% completion rate), and he laid one key pass too.Ruben Dias - 8/10The Portuguese was back to his usual best. He hounded Norwich for the ball, and distributed it brilliantly. The Manchester City defender also laid two key passes, including the assist for Mahrez.Aymeric Laporte - 8/10The mortar to Dias' brick, Laporte complemented his Portuguese counterpart by laying the most accurate passes (109) by a Manchester City player in the match. He was crucial to starting attacks from the back, making nine long balls and scoring Manchester City's third goal too.Joao Cancelo - 8/10Cancelo ran down the left flank and exhibited his strengths, stretching Norwich's defence out wide and helping the Manchester City attack with his teasing crosses. He was formidable off the ball, too, making four interceptions and three tackles.Bernardo Silva - 6/10An uncharacteristically disappointing performance from Silva, who couldn't exert as much influence in the game as he'd have liked. He did not attempt a single effort on goal and laid no key passes either.Rodri - 9/10The architect of Manchester City's resounding victory on the night, the Spaniard ran the show from the centre of the park, dictating his side's tempo and orchestrating their attacking plays. It was a true Man-of-the-Match performance from Rodri.Rodri’s game by numbers vs. Norwich City:100% tackles won90% pass accuracy 85 total touches 10 attempted long passes 8 successful long passes 6 passes into the final third 6 ball recoveries Such a key player for City. 🔑 pic.twitter.com/saJqsQxIPC— Statman Dave (@StatmanDave) August 21, 2021Ilkay Gundogan - 7.5/10The German midfielder worked hard on and off the ball, showing plenty of skill and linking up well with Jack Grealish.Gabriel Jesus - 8.5/10Where was this version of Gabriel Jesus all this time? The Brazilian turned in arguably his best performance of the year, forcing the opening goal and then assisting City's second and fourth goals. Guardiola will be hoping to see more of the same from Jesus going forward.Ferran Torres - 6.5/10The Spanish fireball couldn't light up the Etihad, but that isn't to say he was poor on the night. Torres was key in dragging Norwich defenders wide with his movements, although he was unlucky to have a goal ruled out.Jack Grealish - 7.5/10A goal on his Manchester City home debut - could it have gotten any better? Although it wasn't a strike Grealish would be proud of, he wouldn't care. He provided the thronging fans what they came for.Jack Grealish scores on his home Manchester City debut and hits the Memphis celebration 👉👈 pic.twitter.com/7dRRoDOPCB— B/R Football (@brfootball) August 21, 2021Ratings of Manchester City substitutesRaheem Sterling - 8/10Sterling didn't take long to get on the scoresheet after coming off the bench, producing a classic finish to add gloss to City's scoreline.Raheem Sterling opens his account for the season ✅ pic.twitter.com/YwLimFdtWw— Goal (@goal) August 21, 2021Cole Pamer - 7/10The youngster produced a lively performance, which might convince Pep Guardiola to play him more often.Riyad Mahrez - 8/10He did a Sterling, finding the net with a sublime first-touch finish beyond Krul.
