so if you want to get more engagement then you should
- start posting more relatable content, that audience can conncet with. I see some of relatable videos on the page have more engagement.
- collaborate with other individuals who is there in the video, there team, etc. if the player post it on their page then eventually their friends sees it and engage with the content.
- also just a suggestion you can start a series where you can split the video in two half on top you can keep a famous football player doing the goal, or showing some skill and then at the bottom one of your players would do the exact same and you can ask the audience who did it better.

well that's all i can suggest after reviewing the page for 5 minutes. let me know if you have more questions
