United’s performance against AC Milan in their 4-2 defeat in in Wroclaw, Poland was a reminder that the Red Devils are far from perfect heading into the new season.
Seven months after being sacked by United, Amorim was reunited with his former club for the friendly which saw plenty of action, including six goals - four of which were for his side who dominated the affair.
Amorim had been out of a job since January after he was replaced by Michael Carrick.
However, after taking over AC Milan, life is looking up for the Portuguese tactican who admits he still has love for United even after leaving on bad terms.
"It's a normal game. Since I signed with Milan, I haven't felt anything about Manchester United," Amorim said.
"I'm just proud to have been at Manchester United and I still love Manchester United, but after signing with Milan, I don't feel anything negative about anything because I'm very happy.
"I'm where I should be. So I just want to continue here. I wanted to win a game in pre-season to give our fans a good image."
Man Utd captain Bruno Fernandes greeted Amorim's coaching staff, who were all with him during his time in charge in Manchester, showing the group are still friends despite being let go.
Heading into the new season, United face Hull in their first Premier League game while AC Milan go up against Torino.
