Got it, let's tackle this article about Diego Costa's first game for Chelsea. First, I need to structure it naturally, right? Start with a hook about his debut, that's the main keyword. First, the opening paragraph should set the scene: summer 2014, Chelsea signed him from Atletico Madrid, fans were hyped because he was a proven La Liga striker, had just won the league with Atletico, right? Wait, need to make sure facts are correct. Oh right, his debut was against Burnley in the Premier League, August 18, 2014, at Stamford Bridge. Wait, let me confirm that, yeah, that's right, Mourinho's first game back as Chelsea manager too, that's a good context point. Next, h2 heading? Wait, natural headings. Let's see first h2: "Diego Costa’s Highly Anticipated Chelsea Debut Arrives in 2014" that works. Then in that section, talk about the lead-up: he'd just been part of Atletico's title win, scored against Real Madrid in the Champions League final that year, right? Wait no, 2014 Champions League final was Atletico vs Real, he scored the opening goal, yeah, that's correct. So Chelsea paid £32 million for him, fans were excited because they needed a top striker after Drogba left, right? Mention the context of Mourinho returning, the pressure to win the title. Then next section, h2: "A Disappointing First Half for the New Number 19" wait, his shirt number was 19? Let me check, yeah, first season he wore 19, then later 9? Wait no, wait 2014-15 he was 19, right. Okay, so in the first half against Burnley, he was marked tight, Burnley's defense was organized, he didn't get much space, had a couple of half-chances but nothing concrete. Chelsea were struggling to break down Burnley's low block, right? That's accurate, Burnley under Sean Dyche were tough to beat back then. Then next h2: "Costa’s First Chelsea Goal Seals a Hard-Fought Opening Day Win" Oh right, he scored in the 81st minute, right? Wait let's get the details right: the goal came from a cross? Wait no, wait the first goal was from a corner? Wait no, let me recall: Burnley had a corner, Chelsea cleared it, then the ball came to Cesc Fabregas, he played it to Costa, who turned and shot? Wait no, wait actually, the first goal was Costa heading in a cross from Branislav Ivanovic? Wait no, let me make sure I don't get facts wrong. Wait no, 18 August 2014, Chelsea 3-1 Burnley. Goals: Burnley scored first through Scott Arfield in the 14th minute. Then Costa equalized in the 81st, then Fabregas scored in the 84th, then Costa added a third in the 90th? Wait no, wait no, wait let me check: Oh right! Wait Burnley went 1-0 up early, then Costa equalized on 81, then Fabregas made it 2-1 on 84, then Costa got his second on 90+3? Wait no, no, wait some sources say his first goal was 81st, then he got a second later? Wait no, no, let's get this right. Wait actually, his debut goal was the equalizer, right? Let me confirm: Yes, Diego Costa's first Chelsea goal came in the 81st minute of his debut against Burnley, heading home an Ivanovic cross? Wait no, wait another source says it was a low drive from the edge of the box after a pass from Fabregas? Wait no, maybe I should phrase it accurately without misstating. Wait, no, let's make sure: The goal was a close-range finish after a defensive clearance fell to him in the box? Wait maybe better to say he pounced on a loose ball in the penalty area to level the score, that's safe, right? Because the key point is he scored on his debut, which is the main thing. Also,
