Julen Lopetegui:
Manchester City are the last team you want to face when you're on the brink of being fired but unfortunately it's another painful defeat for the Sevilla boss.
Sevilla finished fourth in La Liga last season but lost central defensive pairing Diego Carlos and Jules Kounde in the summer. One point from four La Liga matches this term is a dreadful start regardless of those losses.
Despite that, there was a positive atmosphere in the Estadio Sanchez Pizjuan for the Champions League opener but boos rang out by full-time.
Lopetegui tried to keep the ball away from the Premier League champions but they were simply overrun and outclassed, looking bereft of confidence.
Riyad Mahrez:
No one in the current squad as scored more Champions League goals than the Algerian winger who has been a major part of runs to the final and semi-finals in the past two years.
But there was no recall into the starting line-up for a player who has started just two of Manchester City's six Premier League matches this season.
Mahrez's last start was the victory over Crystal Palace but he was hauled off with Manchester City trailing 2-1 and has now not started the three matches since.
Jack Grealish came straight back into the side after recovering from injury and Mahrez is facing a fight to win back his place.
Antonio Conte:
The Tottenham boss was unhappy with the fixture schedule that sees his side go to the Etihad Stadium between Champions League games against Marseille and Sporting CP.
Adding to his anger was the fact that Manchester City had an extra 24 hours to prepare for the fixture, although his team remained in England at least.
But he will be further frustrated that City weren't stretched more in Sevilla, with the game resembling a training drill of attack versus defence on occasions, while key players were taken off early with the game won.
Tottenham won home and away against City last season and Conte will have to produce something even more special to replicate that.
