Manchester United moved quickly and decisively to temporarily replace Christian Eriksen during the January window - but Erik ten Hag and his squad have yet to fully reap the benefits of that transfer decision.
As the mid-season transfer deadline loomed, Marcel Sabitzer was identified as a perfect stop-gap after Eriksen saw his campaign derailed by an ankle injury. However, the on-loan Bayern Munich ace has yet to be afforded the biggest luxury any United player can have right now: playing alongside Casemiro.
Having long since been a 'problem' position at Old Trafford, Casemiro's impact in the United engine room this season has, quite simply, been staggering. Not only have his individual performances been brilliant, the Brazilian powerhouse has also undeniably brought the best out of others around him.
