Manchester United appoint Jose Mourinho on three-year deal
Jose Mourinho has described his appointment as Manchester United manager as a "special honour" after signing a three-year contract.
United formally announced the 53-year-old as Louis van Gaal's replacement as manager after a week of negotiations.
The club tweeted footage of Mourinho holding the United shirt and confirmed his contract includes an option to stay at Old Trafford until at least 2020.
Negotiations between Mourinho and the Red Devils had reportedly been delayed over several issues, including images rights that his former club Chelsea still owned.
It was reported late Thursday that an agreement was in place ahead of Friday morning's official confirmation.
The man who famously titled himself as the Special One upon arriving in English football in 2004 said it was a "special honour" to manage the country's most successful club.
Manchester United executive vice-chairman Ed Woodward hailed Mourinho as the world's best.
Along with his success in the Premier League during two spells with Chelsea, Mourinho has won the Champions League twice - in 2004 with Porto and 2010 with Inter Milan - and boasts league championships in four different countries, including the La Liga title while at Real Madrid.
He led Chelsea to the 2014-15 title but was sacked by the club in December after losing nine out of 16 league games.
Mourinho was consistently touted as the favourite to replace Van Gaal at Old Trafford through the rest of a season that disappointed many United fans.
The Dutchman was sacked last weekend - a day after leading the club to FA Cup glory - having failed to secure the club's main objective of Champions League qualification in the league.
Club shirt sponsor Adidas was quick to welcome the new manager.
