Rangers host St Mirren and Celtic travel to face St Johnstone on Wednesday in Scottish Premiership fixtures, with both Old Firm sides looking to build momentum ahead of their Premier Sports Cup quarter-final meeting at Ibrox on Sunday. Rangers can move into second place with a fourth successive win, having steadied under Derek McInnes after a rocky start to the season, while Celtic remain unbeaten domestically and have strengthened their squad with late transfer window signings.

Rangers currently trail third-placed St Mirren only on goal difference, with the Paisley side impressing under manager of the month Craig McLeish, though they were thrashed 5-0 by Rangers in the League Cup last month. A settled Rangers defence featuring debutant James Penrice has underpinned recent wins over Aberdeen, Falkirk and Motherwell, despite the loss of injured striker Lawrence Shankland for up to four months. Celtic, who beat St Mirren narrowly at the weekend thanks to Yang Hyun-jun, must now cope without the winger as he departs for the Asian Games with South Korea, with Sebastian Tounekti or Shim Mheuka among the options to replace him, while Kasper Hogh and Kieran Tierney are nearing returns from injury.
