St Mirren are reportedly set to sign Louis Jackson from Manchester United on a permanent deal. The 20-year-old Scotland Under-19 international is expected to undergo a medical with the club on Thursday, according to the Renfrewshire Gazette.

What does Louis Jackson bring to St Mirren’s defence?

Louis Jackson, a product of Manchester United’s academy, has represented Scotland at Under-19 level and is viewed as a promising centre-back with good reading of the game. His arrival would add youth and potential to a St Mirren backline that has kept two clean sheets in the opening two Premiership games. The club currently sits third in the table with six points from two wins, having scored three and conceded none.

How does this fit with St Mirren’s recent transfer activity?

This potential signing follows the loan arrival of Calvin Ramsay from Liverpool earlier in the summer. Ramsay, born in Aberdeen and a former Reds Champions League debutant against Napoli, has already featured for St Mirren this season. Both moves reflect the club’s strategy of securing young talent with Premier League experience on temporary or permanent bases.

What are the implications for the squad and upcoming fixtures?

With Jackson expected to join, St Mirren could bolster their defensive options ahead of the home fixture against Motherwell on 2026-08-30, a side currently fourth in the Premiership. The club’s strong start, including a perfect defensive record so far, suggests the timing of this signing aims to maintain momentum as they push for a top-six finish.

What happens next in the transfer process?

The club will now await the outcome of Jackson’s medical on Thursday before finalising the permanent deal. If cleared, the teenager will sign a contract and begin training with the squad immediately. St Mirren’s focus remains on integrating new signings while continuing their strong league form, with updates available via our squad and fixtures pages.
