The Hammers claimed a 3-1 win against the Bluebirds at the London Stadium. It was a fairly bizarre game, with Cardiff seeing an early penalty saved before Lucas Perez bagged a brace and Michail Antonio scored to put the Hammers 3-0 up within 12 minutes of the deadlock being broken.
Warnock's men would score late on to make the scoreline look more respectable. But when asked about strengthening the defence in January, the Cardiff boss used Anderson's performance as an indicator of how the result may have flattered the home side.
"Well I thought I've never seen (Felipe) Anderson as quiet this season. He ripped Newcastle to pieces and yes he lost Bruno once but I thought Morrison and Bamba did well tonight, I can't remember the strikers doing much at all," he said, as reported by Wales Online.
In fairness to Anderson, he is entitled to a quiet game after a superb recent run. He had scored four goals in his previous four games to really spearhead West Ham's turnaround.
And what will please Manuel Pellegrini is that other players stepped up. West Ham fans would have been forgiven for not believing it had they been told before the game that they would win 3-1 and none of the goals or assists would come from Anderson, Javier Hernandez or Marko Arnautovic.
Perez's two goals could be huge for his confidence, while Robert Snodgrass' two assists make the Scotland international a surprise front-runner in that particular area this season.
