Ole Gunnar Solskjaer is still trying to strike a balance between defence and attack in the biggest matches as Manchester United head to Chelsea.
United have been much improved this season to enter the title race, albeit now sitting 10 points off the pace.
While there have been costly home defeats, the chief issue for Solskjaer's side has been the struggles against their 'big six' rivals, too often failing to turn draws into wins.
United's defence has let them down at times, too, and Solskjaer is keen to see them turn the corner to maintain their outside title hopes.
