The 39-year-old will start working at Old Trafford on November 11, with the task of reforming the squad and creating impressive performances. Man United are currently 13th in the Premier League table after a disappointing start.
Amorim is considered one of the most talented coaches in Europe at the moment. However, the current Man United squad is still lacking, despite strong investment in recent years.
Amorim will be keen to strengthen the Red Devils' defence, especially the centre-back position. New signing Leny Yoro has yet to make an appearance for Man United, while Matthijs de Ligt has also been unimpressive.
Jarrad Branthwaite could be a realistic option to add much-needed depth to Amorim's defence. Coach Sean Dyche admitted Everton are willing to sell the centre-back. They will need as much money as possible to strengthen their squad in the relegation battle.
Branthwaite has been out for the season after struggling with injuries. This could reduce his value and make it easier for Man United to negotiate. Everton have previously rejected two offers to buy the England international from the Red Devils. With Amorim using a 3-man defense, Branthwaite can play alongside De Ligt and Lisandro Martinez.
Another defender being linked with Man United is Bayern Munich's Alphonso Davies. The Canadian's contract expires at the end of the season, sparking speculation that Man United could tempt Bayern with an offer in January.
Davies remains a key player for the "Gray Tigers" and has started 7 Bundesliga games this season. However, with Luke Shaw and Tyrell Malacia both struggling with injuries, Amorim will be determined to sign Davies.
Man United are also in dire need of a reliable goalscorer. This has been proven with Alejandro Garnacho currently the team's top scorer with 6 goals.
The Old Trafford side have been heavily linked with Leroy Sane, whose Bayern contract expires next summer. Amorim will try to sign the former Man City star at a reasonable price.
Sane has yet to make his Bundesliga debut under Vincent Kompany this season, making just five substitute appearances. However, the German player still scored 3 goals in all competitions.
The fourth player United have eyes on is Sporting Lisbon youngster Geovany Quenda. The 17-year-old attracted the attention of many clubs after shining in the 4-1 victory over Man City in the Champions League.
According to Men, Man United has added this winger to the transfer list. However, they could have to pay around £84 million to make Quenda the latest Sporting star to move to Old Trafford, following Cristiano Ronaldo, Nani and Bruno Fernandes.
