Transfer window enters final stretch: 30 star players still without a club

It was not possible to create a summary of this article, as only the title and subtitle were provided ("Transfer window enters final stretch: 30 star players still without a club" and "There are still several big names available at zero cost"), but the body of the article with detailed information about which players are involved and the complete context was not included. In order for me to write a factual summary of up to 4 paragraphs using only information present in the article, the full content of the article would need to be provided.
