First, the user wants an original article for the keyword "Diego Costa Chelsea Appearances". I need to write an article that is 600 to 900 words, with natural headings, and avoid unsupported claims. I must not mention that it's AI-generated. The provided context includes snippets like: - "The big Spanish striker notched 58 goals and made 120" - "Deadly" - "When" - "Join to Goal Zone Facebook : https://www.facebook.com/Goalzoneyt." - "Twitter : https://twitter.com/CFCVideos ▷ Facebok : https://www.facebook.com/CFCVideos14 ▷" - "Here are" - "On this day" - "THE ENGLISH LEGENDS CLASSIC ON FIRE AS HAZARD & DIEGO COSTA RETURN TO CHELSEA!" I need to use this context when useful. The context seems to be from social media posts or promotional material, so I can incorporate it sparingly to make the article relevant. The keyword is "Diego Costa Chelsea Appearances", so the article should focus on his appearances for Chelsea, including his goals, impact, and memorable moments. Structure the article: - Introduction: Diego Costa's time at Chelsea, his significance. - Body: His statistics (58 goals, 120 appearances), his playing style (deadly), key moments, and perhaps his return with Hazard in a legends classic. - Conclusion: His legacy at Chelsea. Since the context mentions "THE ENGLISH LEGENDS CLASSIC ON FIRE AS HAZARD & DIEGO COSTA RETURN TO CHELSEA!", I can include that as a recent event or hypothetical scenario. But I need to ensure it's plausible and not unsupported. I can write about a charity match or legend game. Now, for natural headings: I'll use H2 and H3 tags. For example: - Introduction - Diego Costa's Chelsea Statistics - The Deadly Striker in Action - Key Memories at Stamford Bridge - Return of the Legends Ensure the article flows well and is engaging. Word count: 600-900 words. I need to write without markdown fences, only safe HTML.

For example, the Facebook and Twitter links might be for promoting the article, but I should include them in a SEO section or something similar. However, the article is about Diego Costa, so I can put the links in a footer or after the article if needed. The user said "use this context when useful", but I don't need to force it. I'll include the social media links in the article if appropriate, perhaps in a section about fan engagement. To avoid unsupported claims, stick to stats like 58 goals and 120 appearances. Don't make up awards or records. Now, write the full article in HTML. Let me write step by step. First, set the HTML tags.
