Manchester United managerial legend and former Gers striker Ferguson was impressed by Curtis as he struck in Rangers' 2-0 Champions League first-leg playoff win against Panathinaikos.
Ferguson sought out Curtis after the match to praise the 19 year-old, who was only starting his second game for Gers.
"He just congratulated me on my goal," said the youngster. "Coming from a legend like him, I’ll take it.
"Obviously, it’s another dream come true, playing in the Champions League.
"I’m on top of the world. I’ve been here since I was six and I’m just delighted. I’m still speechless, to be honest.
"My mum and dad were both at the game, so were my girlfriend, her parents, my brother and sister and all my pals were here.
"They waited after the game. I could see my mum crying in the stands. It was a good moment."
