St Mirren is battling to sign St Johnstone goalkeeper Ross Sinclair on a permanent deal. The 25-year-old was in demand last season after a successful emergency loan spell in Paisley. According to a report from the Daily Record, head coach Craig McLeish wants to bring Sinclair back to the club ahead of the new season. However, he will face competition from Dundee United. McLeish is keen to wrap up a deal for Sinclair after seeing Shamal George return to his parent club, Wycombe Wanderers. Meanwhile, St Mirren skipper Mark O'Hara could leave the club this month despite being offered an extension by the Buddies. His contract is due to expire at SMiSA Stadium this month, and the club want to extend his stay. However, they face stiff competition from clubs in England, Europe, and Asia, as well as from Scottish Premiership rivals Kilmarnock. The transfer window is set to open in just five days, and the summer transfer reports, rumours, and confirmed transfer deals are fully underway as clubs across the country build their squads ahead of the 2026/27 campaign. In Thursday morning's transfer bulletin, we've got the latest transfer reports from Celtic, Rangers, St Mirren, and the Scotland national team.
