Mourinho made his name during a spell with Porto between 2002 and 2004 where he won six trophies, including the Champions League in 2003-04.

Since leaving his homeland in 2004, Mourinho has managed Chelsea (twice), Inter Milan, Real Madrid, Manchester United, Tottenham Hotspur, Roma and Fenerbahce.

Mourinho said "none of the other giant clubs" for whom he has worked since he left Benfica have made his feel as "honoured, responsible or motivated".

He added he returns as a "less self-centred" person who thinks more about the "joy" he can bring to others.

After sacking Lage on Tuesday, Benfica president Rui Costa said the new manager must have the "profile of a winner".

Mourinho certainly fits that brief, having won 21 major trophies, with his most recent success coming in the Conference League with Roma in 2022.

That haul includes two Champions League crowns and eight league titles in four different countries, though his last trophy before success with Roma was the 2017 Europa League at Manchester United.

"In some people's minds, I have two resumes - one that lasted a certain period and another that represents, let's say, a less happy phase of my career," said Mourinho.

He added that in this "negative" part of his career he has reached two European finals in the last five years, with Roma losing to Sevilla in the 2023 Europa League final the year after their Conference League triumph.

Benfica also travel to Newcastle and host another of his former teams Real Madrid later in the league phase of the competition.

They finished second in the Portuguese top flight last season and last won the title in 2022-23.

Mourinho endured a turbulent time in Turkey and was often at odds with the standard of refereeing.

In November, Mourinho blamed Fenerbahce for only telling him "half of the truth" about the level of officiating and said referee Atilla Karaoglan was "man of the match" after his side scored late to beat Trabzonspor.

He filed a lawsuit against rival club Galatasaray in February after they accused him of making racist statements.

When Mourinho was appointed Fenerbahce manager in June 2024, millions of fans dared to dream. One of the world's most famous coaches had arrived to end a decade-long title drought and perhaps deliver glory in Europe.

But that dream quickly collapsed.

More than a year on, those hopes have largely turned into frustration. Mourinho failed to win an Istanbul derby and could not deliver the league title.

And now he has joined the very club that knocked Fenerbahce out of the Champions League play-offs.

For many Fenerbahce supporters, this feels like a betrayal. They believe Mourinho not only abandoned them, but played them for fools.

Gokay, a lifelong Fenerbahce supporter, told BBC Sport: "From the very first day, Mourinho was interested in everything except football.

"He played down Turkish football and served up one of the worst styles of play in Fenerbahce's history."
