Manchester United manager Jose Mourinho has cited his team's hectic schedule as a reason for leaving Eric Bailly out of West Bromwich Albion tie.
Victor Lindelof was preferred to Bailly - who put in a decent shift last week against the Citizens - in Sunday's encounter and the Portuguese tactician has explained the reason for the tweak.
"A decision again. Victor played the match against Swansea at home and it was very suited to his qualities," Mourinho told club website.
"Normally, we are going to have more of the ball and, normally, it’s when we need somebody from the back to add extra technical quality in the middle of the back [four].
"We have three matches in a week. Bournemouth in a few days [Wednesday night] then [Tottenham] Spurs after a few days again. In that semi-final, they are having one day extra to us to recover so I need also to think about that."
Bailly will be hoping to make his 12th Premier League appearance of the season when Manchester United visit AFC Bournemouth on Wednesday.
