Mbunya Ahave signed 16-year-old Cambridge United whizkid Mbunya Alemanji for £70,000.
The 16-year-old has signed a three-year contract with the Serie A club, who recruited the forward without having seen him play in the flesh.
The League Two side will receive about £70,000 in compensation and Alemanji is set to link up with Roma's Under-17 squad initially.
"It is a big move but I'm just trying to prove why I'm there," he said.
"My friends have been saying to me: 'Do you realise you're at AS Roma?' I'm just trying to keep calm."
Alemanji was born in Germany but moved to England at the age of three.
The teenager had only been with Cambridge for three years after an intial six-week trial as a 13-year-old.
Alemanji shares an agent with former Manchester United and current Lyon star Memphis Depay.
