James Milner didn't know what had hit him. He was up against a man 16 years his junior and, to put it mildly, he got rinsed. Jeremy Doku repeatedly tore his way past the 37-year-old in a torturous first half for Brighton and a wonderful opening 45 minutes for Manchester City.
Doku handed Julian Alvarez the opening goal on a plate and could have found the net once or twice if his shooting had been ever so slightly sharper. Every time he got on the ball, City fans sensed something was about to happen. They were enthralled by his every move.
The Belgian is the type of player fans want to see when they go to matches, the type of player that gets you out of your seat and justifies the ticket price. He is also the type of player who can prise open tight defences and win a match in one flash of brilliance.
In other words, he is exactly the type of player who should be starting Sunday's derby against Manchester United. And if that means a place on the bench for Jack Grealish, then so be it...
