This could be Bernardo Silva's moment after his scintillating start to the season to make the grade from City's favourite luxury item on the bench to the main man.
"Big congratulations to him", said Guardiola, reporting that Silva had overcome a slight knock that kept him out of the Arsenal match and was back in contention for Sunday's game. I never saw him like this since I was here, he is in an incredible condition with the ball and without the ball.
Ten minutes before the break, City made it three as Hamer spilled a low cross from Benjamin Mendy and Aguero tapped home - but Huddersfield got one back, Stankovic stabbing home after Mounie had flicked on.
For most clubs, losing a player with the quality of Kevin De Bruyne would be a potentially fatal blow to their title hopes but City have the resources to cope.
The Argentinian lured Huddersfield's goalkeeper, Ben Hamer, out of goal and with him caught in no man's land, Aguero lifted it over him. Aguero and Jesus dropped deep to pull Huddersfield apart, John Stones and Aymeric Laporte spent more time in the opposition third than their own while both Silva stars picked and probed all afternoon. With Huddersfield likely to sit back and defend, Silva will be charged with unlocking the defence with a key pass.
Manchester City will play their first home game of the 2018/2019 season, against a resolute Huddersfield side who will be looking to frustrate the reigning league champions.
Huddersfield worked miracles staying in the Premier League last season, but it might be an even greater surprise if they are to stay out of the bottom three a second year.
"We met [Mateo] two days ago, now he was in the locker room with all the squad, the family was there". It's a tough opening round of games for David Wagner's team but will draw some confidence from last seasons 0-0 draw at the Etihad against the Citizens.
De Bruyne played 63 matches for club and country last season, which is likely to have contributed to the injury, according to Guardiola.
