Martin O'Neill considers system changes for Celtic ahead of St Johnstone

Celtic manager Martin O'Neill is evaluating tactical adjustments for Wednesday's Premiership match at St Johnstone. The manager is managing the return of record signing Kasper Hogh alongside the absence of midfielder Hyun-jun Yang, who is currently on international duty with South Korea. Following a 2-1 victory over St Mirren on Saturday, O'Neill indicated he might shift to a 3-5-2 formation to accommodate his best available players. While Camilo Duran has performed well in the center-forward role, O'Neill also has options including loan signing Shim Mheuka, who has impressed in limited appearances. Defender Kieran Tierney is undergoing fitness assessments, and Callum Osmand remains sidelined with an ankle injury. The match at McDiarmid Park kicks off at 8:00pm.
