Erik ten Hag wants to give Casemiro "time" before handing him his Manchester United debut, as he benched the £60million signing alongside Cristiano Ronaldo against Southampton.
Casemiro's eye-watering transfer deal was completed earlier this week, while Ronaldo's future at the club hangs in the balance. As the Red Devils head to St Mary's looking to make it back-to-back Premier League wins, Ten Hag opted for an unchanged starting XI from Monday's epic 2-1 victory over Liverpool.
Club captain Harry Maguire also remains on the bench, having been warned by Ten Hag over his uncertain future with the armband, despite Southampton manager Ralph Hasenhuttl hinting that his team have a plan to exploit his centre-back replacement, Lisandro Martinez. Anthony Martial has picked up another injury, while Victor Lindelof still isn't fit to feature.
