Pogba was United's marquee signing for 2016-17 – Mourinho's first season in charge at the club – and helped the Red Devils to a Europa League title that campaign.
Yet Mourinho's second term failed to live up to expectations and, after a difficult start to the 2018-19 season, the former Chelsea and Real Madrid manager was dismissed, with Solskjaer replacing him, initially on an interim basis before taking up the role full time.
Mourinho's relationship with members of United's squad was said to have deteriorated, with an apparent training ground argument with Pogba coming after the France star was stripped of a vice-captaincy role in September 2018.
Though Mourinho has since left United, Pogba's future remains unclear.
