Sergio Aguero and Ilkay Gundogan each scored braces in either half to end Manchester City's six-game winless run in all competitions with a 4-0 victory at West Brom.
Having started only three of the matches in question, Aguero was without a goal in the same period, but a pair of fine finishes took him to seven for the season in the Premier League and 13 overall.
