Southampton's hopes of a last-minute move for Brandon Williams have been punctured after Manchester United changed their mind on letting him leave on loan.

According to The Mirror's David McDonnell, Ole Gunnar Solskjaer has no intention of sanctioning a move away from Old Trafford for the young defender. The Saints were reportedly keen on bringing Williams to St Mary's in a short-term move to help bolster their options across the backline. However, a deadline day curveball leaves Ralph Hasenhuttl scrambling to find another potential full-back who fits the bill.

Hasenhuttl concerns

Despite having a well-stocked defensive roster, the Southampton boss is seemingly in the market for another full-back. Williams, who can operate on both the right and left flank, would've given Hasenhuttl a lot to think about in terms of his starting line-ups. His interest in a player who is versatile across the back-line could hint that he has little faith in the club's current young full-backs.

Yan Valery, 21, and Jake Vokins, 20, are two of the club's defensive fringe players currently in the senior team. However, neither have played a single minute of Premier League football this season. The arrival of Kyle Walker-Peters sees him become one of the first names on Hasenhuttl's team-sheet, with veteran Ryan Bertrand opposite him.

Adding Williams to his options would have provided more depth for catering to certain opposition sides. The 20-year-old has featured in Man United's Carabao Cup run this season, keeping two clean sheets and bagging himself an assist. He is already ahead of most other young full-backs after notching an impressive 38 senior appearances for the Red Devils, with a goal and three assists to boot (via Transfermarkt).

Southampton have won two of their four games played so far and sit in a respectable 11th place in the table. Will any last-gasp loan deals sneak through the door to help shape Hasenhuttl's season?
