The Seagulls face Newcastle at Falmer Stadium on Saturday after that memorable 2-1 win at Old Trafford against United nearly a week ago.
"The result on Sunday was very nice!" said Potter of his side's opening-weekend triumph.
You can't be perfect all the time, I thought we suffered and we had to get some small margins - which we didn't get.
"But we performed well, kept our heads and focused on what we had to do."
One of Potter's standout players at Old Trafford on Sunday was striker Danny Welbeck.
The former United player was out of contract at the end of last season but ended up re-signing with Brighton.
"Danny is in the best condition he's been in since I've been working with him," Potter said of the 31-year-old attacker.
"Everyone looks up to him and he's playing really well. We're just happy he's enjoying his football.
Moises Caicedo was another of Potter's squad to catch the Brighton manager's eye after the away victory.
However, Potter does not want to push the 20-year-old Ecuadorian midfielder unnecessarily while he still continues to adjust to life in the Premier League.
"Moises is playing well and enjoying his football. We rate him a lot," he said.
"He's adapted really well and is performing at a good level, but we don't want to put too much pressure on him."
