In what was an incredibly successful month, Manchester United's December had some extreme highs. The Red Devils brushed aside both Tottenham and Manchester City, before ending 2019 with consecutive wins over Newcastle and Burnley.
The pick-up in form means Ole Gunnar Solskjaer's side have risen up to the fifth in the Premier League table, and just four points behind fourth-placed Chelsea. Their hunt for Champions League qualification is well and truly on, and they can make another major statement in that race with a victory over Arsenal on New Year's Day.

With such a quick turnaround from their clash at Turf Moor to the one at the Emirates, Solskjaer may be keen to make changes and freshen things up. And with that in mind, below is a look at how United could line up.
Having made a fine save from Phil Bardsley at the weekend, David de Gea showed signs of being back to his best. In front of him, the likes of Aaron Wan-Bissaka and Luke Shaw should replace both Ashley Young and Brandon Williams in the starting line-up for the trip to north London.
And in midfield, following Solskjaer's confirmation that Scott McTominay will be missing from first-team action for the next few weeks, Fred and Nemanja Matic should keep their places in central midfield. Ahead of them, Jesse Lingard could come back into the team, with the England international enjoying a particularly fruitful time of things against Arsenal in his career - he has four goals and one assist in just six games against the Gunners.

And whilst Daniel James performed well against Burnley, it was a bruising encounter for the Wales international. Mason Greenwood could therefore earn a recall and take his place alongside Marcus Rashford and Anthony Martial as United look to head back to Manchester with all three points.
