The Frenchman, soon after sending a shot narrowly wide, went down before gingerly hobbling off during the closing stages of the game.
He had, up to that point, dominated proceedings in midfield against Sean Dyche’s men with a series of powerful turns and passes.
Mourinho, when asked about Pogba’s injury, couldn’t confirm whether the 23-year-old was injured or simply fatigued after featuring in all of Man United’s last six games.
“I don’t know,” he said. “Dead he is for sure, if he’s injured or if it’s just the super accumulation of fatigue in the muscles, I don’t know.
“But as I was saying, if he cannot play Thursday he cannot play Thursday, we play another one and we don’t cry, like we didn’t today.”
This was indeed a gloomy warning for Mourinho on what turned out to be an otherwise trouble free afternoon in the Lancashire sun. The Portuguese ought to be wary of the way in which Pogba, following an accumulation of games, suffered a hamstring knock against FC Rostov back in March that ruled him out for three weeks.
Whether the same affliction has happened against Burnley remains to be seen, but Mourinho will nonetheless need to tread a fine line between fielding his ideal midfield and overworking key players towards the end of the season.
