SUMMARY:
Sheffield United are reportedly in talks with Leicester City over a potential transfer for defender Harry Souttar, according to the BBC. Souttar, an Australia international centre-back, has been with Leicester City, and a move to Sheffield United would represent a fresh chapter as both clubs navigate their squad-building plans outside the Premier League.

Specific details such as fee, contract length, or the stage of negotiations were not available in the supplied text, as the article content could not be retrieved (only a cookie-consent page was returned). I'd recommend checking the BBC Sport website directly for confirmed figures and quotes before treating these details as final.
