One of Ole Gunnar Solskjaer’s big Manchester United decisions against PSG this week is at centre-back.
Victor Lindelöf is an automatic pick, the question is who will partner him?
Eric Bailly is his most talented potential partner, but the pair have not played together regularly.
Phil Jones has enjoyed the most game time alongside Lindelöf and has begun to find his form and confidence again.
Chris Smalling also returned at the weekend and earned praise from Solskjaer for his performance.

We put the question out on Twitter to fans with a poll, and the response was overwhelming in Bailly’s favour.
More than 1,800 supporters responded, with Bailly amassing 74 per cent of the vote.
All three defenders can be erratic, and face a tough test up against Kylian Mbappe.
Bailly has the pace and athleticism to best match Mbappe and this could be crucial tomorrow night at Old Trafford.
The Ivorian has performed strongly in Europe in the past for United, starring in the 2016/17 Europa League campaign, and will be up for the test ahead.

It is no guarantee that he starts of course, and would not be a surprise to see Jones or Smalling get the nod.

That Jones got as many votes as he did is testament to his recent return to form.
The fact that Bailly was rested at the weekend along with Lindelöf offers a clue that the 24-year-old is the player Solskjaer will choose.
