1. **Analyze the Request:** * **Keyword:** "Diego Costa Chelsea Card" * **Context provided:** "The big Spanish striker notched 58 goals and made 120 appearances for the Blues over a three-and-a-half year spell at Stamford...", "Deadly", "Here are", "Diego Costa vs. Vincent Kompany", "Red", "When", "Chelsea", "On this day". * **Requirements:** 600-900 words, natural headings, HTML format (h2, h3, p, ul, ol, li, strong, em), safe HTML only, no markdown fences, concise/factual/SEO-friendly, original content, no AI mention. 2. **Determine the Topic & Angle:** * The keyword "Diego Costa Chelsea Card" could refer to a few things: * A trading card (Panini, Topps, etc.). * A literal "red card" (he got a few). * A metaphorical "wild card" (his unpredictable nature). * Given the context ("Deadly", "58 goals", "Red", "Vincent Kompany"), the article should discuss his legacy at Chelsea, his aggressive style (red cards), and the value of his trading cards for collectors.
