The United manager was dismissed on Tuesday morning following a 3-1 defeat at Anfield on Sunday – and Pogba was quick to react to the news.
The France international shared a photograph of himself smirking at the camera along with the tagline: “caption this”.
Pogba was quick to delete the photograph but not before it had garnered a huge reaction across social media.
Mourinho’s relationship with Pogba has come under particular scrutiny in recent weeks, with the World Cup winner repeatedly left on the substitute’s bench.
Mourinho joined United in May 2016 and guided them to success in the Community Shield, League Cup and Europa League in his first season.
But he was unable to deliver success in the Premier League, with United finishing sixth in 2017, and second - but 19 points adrift of runaway champions Manchester City - in 2018.
Michael Carrick will take charge of training today, before an interim boss is appointed. That move is expected to happen before the end of the week.
In January this year United handed Mourinho a contract extension until 2020, but have now parted with the former Chelsea, Inter Milan and Real Madrid boss.
