The Red Devils boss extended his stay for another two and a half seasons following a promising start to his Old Trafford career after Mourinho won two trophies last term.
Manchester United were 3-2 winners against Southampton in the League Cup final before a 2-0 victory over Dutch giants Ajax in the Europa League final in Stockholm.
The only blemish on Mourinho’s record on his first season at Old Trafford was a disappointing sixth-placed finish in the Premier League table last season.
Manchester United haven’t won the Premier League title since 2013 when Sir Alex Ferguson was in charge at Old Trafford.
Mourinho’s biggest challenge will be restoring the Red Devils to the top of the Premier League but overcoming Pep Guardiola’s Manchester City side will prove a difficult task.
Manchester United chief executive Woodward shed light on the reasons behind the Red Devils’ decision to extend Mourinho’s contract until 2020.
“Jose has already achieved a great deal as Manchester United manager and I am delighted that he has agreed to extend his commitment until at least 2020,” Woodward told Man United’s website.
“His work rate and professionalism are exceptional and he has embraced the club’s desire to promote top quality young players to the first team.
“He has brought an energy and a sense of purpose to everything that he does and I am sure that will continue to bring results for the fans and the club.”
Manchester United are in second place in the Premier League table but 12 points behind leaders Manchester City.
