With the points all but secured by Toure’s goal, attention for man City fans switched to Pablo Zabeleta’s big send-off.
After nine years with City in which he won every domestic trophy, the 32-year-old Argentina defender is leaving the club at the end of the season.
He started on the bench but the home fans sang his name from kick-off, gave him his first standing ovation of the night in the first half and then exploded into noise when he began warming up.
The ground rose to applaud him on to the pitch when he replaced David Silva on the hour mark, and then cheered every time he touched the ball.
Zabaleta ended the game wearing the captain’s armband after Vincent Kompany was substituted and West Brom’s belated fightback never threatened to ruin his night.
