Roma forward Henrikh Mkhitaryan has already outlined what it’s like to work under his newly-appointed manager.
However, the charismatic Portuguese – sacked by Tottenham last month – won’t return to the dugout right away.
Indeed, the 58-year-old is set to step into the Serie A hot-seat in time for next season, having initially been backed to take a prolonged break from football.
Although he will have no direct input against United – where he spent just over two years between 2016 and 2018 – Mourinho’s appointment provides another intriguing subplot ahead of Thursday night’s return leg.
United have all-but confirmed their place in next month’s Europa League final as they bid to replicate their triumph in the same competition, under Mourinho, from four years ago.
Set to be reunited with Chris Smalling and Henrikh Mkhitaryan, the Armenian captain – who Mourinho both signed and sold during his tenure at Old Trafford – has already spoken out about their time together in the Premier League.
During an interview with The Athletic ahead of the first leg last Thursday night, Mkhitaryan said: “I never regret my decisions, At that time, he [Mourinho] was one of the most successful coaches in the world, and I think he was the coach with the most trophies. So that was a different experience.
“It was very hard, but I learned a lot as well. I learned how to defend, how to help the team. It was not only about scoring goals and making assists.”

Mkhitaryan, whose current deal in the Italian capital expires at the end of this season – although there is an option to extend those terms – added: “It was more about the team winning, so it doesn’t matter who scored.
“We had to win together. It didn’t matter who made the assist, we must always be happy that we won the game.
“What I want to say is that I had a hard time, but after the first two or three months there, I had a very good time. I won three trophies with the club, which was amazing. You know, some players have been playing in Manchester for ages, but they haven’t won anything.”
