The France international midfielder is a doubt for Thursday's clash at the Etihad Stadium after being forced off in a 2-0 victory over Burnley
Jose Mourinho confirmed Paul Pogba is a doubt for the Manchester derby in the Premier League on Thursday after suffering an injury in the 2-0 win at Burnley.
Anthony Martial and Wayne Rooney goals saw United move to within a point of fourth-placed Manchester City ahead of the potentially critical derby, but Pogba limped off in the closing minutes.
United are already without Zlatan Ibrahimovic and Marcos Rojo after the pair suffered "significant" knee ligament damage in the Europa League quarter-final against Anderlecht and Mourinho is unsure whether Pogba will recover in time to face City.
