Drafting a news release

I'm focusing on producing a polished news release that includes five headlines and social media captions. To simplify, I think providing two deliverables—a set of headlines and a 120-character brief—might be the way to go. The brief highlights that Shanghai Shenhua has renewed their coach, Slutsky, emphasizing targets like the AFC Champions League and strategic signings from the Brazilian market. The headlines are crafted to reflect this development while avoiding too much specificity on official statements. Let's keep things concise and straightforward!
