"I won't say it was a surprise [because] we did prepare well," he responded when asked after the match whether he had expected to win like that.
"It's not easy, even if the scoreline is 3-0, to beat Home because they are well organised but again, credit to my boys because they fought very hard.
"We did a lot of analysis on what went wrong in the past and our hard training paid off."
Even as Amin hailed the Cheetahs' character and discipline, Home's assistant coach Aidil Sharin lamented their off-colour performance.
"You can see that today the team is not playing its usual pressing game, it was the opposite as they did it against us until [the end of the] 90 minutes against us," he said.
"You can see they were more hungry than us."
Standing in for head coach Lee Lim Saeng, which was hardly a surprise to the media present, Aidil (right) also went on to acknowledge that the defeat was one of their worst ever.
"It (the losing margin) could have been more, to be frank, and it is one of our worst defeats, especially playing at home ground," he said.
"We just wanted to get three points, that’s our plan and we knew it was not going to be easy because we were defeated by 10-man Hougang in the first round and we knew they were going to come at us."
Amin's charges certainly flew at the Protectors from the first whistle after he had noticed in their pre-game preparations that they tended to leave space in their back-line, which suited Hougang's counter-attacking strategy.
Having beaten Harimau Muda in their previous game to end a seven-game losing streak, Amin pointed out that this victory only served to add to their confidence.
"As I've said earlier, we will take it one game at a time and I'm pleased with our performance," he said.
"We want to win the next game for sure so hopefully in the next game against Warriors FC away, we can maintain our performance."Aidil also gave credit to his team's conquerors.
"It was just unfortunate we didn’t play well and we have to congratulate them because they did very well to come here and get three points and three goals," he concluded.
