Eric Bailly's omission from Manchester United's squad has been as a result of difficult centre-back combinations, according to manager Jose Mourinho.
The 24-year-old's last appearance was against Newcastle United on October 6 when he was replaced in the 19th minute as the Red Devils rallied back to defeat their visitors 3-2 at Old Trafford.
Chris Smalling and Victor Lindelof have been regular fixtures in United's defensive set-up and have formed a strong bond that leaves the former Villarreal player struggling for opportunities.

"And then we have Phil, Rojo and Eric. And I try to make them motivated and to make them motivated that I cannot select the same all of the time. If I put Phil Jones on the bench five matches in a row and never Rojo and never Eric. So I am trying to select on the matches, the situation.
"Marcos is injured a lot of [the] time, so he is a little bit behind. But between Phil and Eric we are working like this, when we decide to make a rotation, we will make, when we need to play them, they are there to play."
Bailly has played just seven matches across all competitions this season - five coming in the Premier League.
