Petrucci's Man Utd move earns Dad new job
But it is the chance for his father to work in the gardens of Manchester that have helped to swing the deal.
Petrucci said: "Going to play for the strongest club in the world is a great opportunity for me. It was hard to say no, even though I am a Roma fan.
But United have offered my father Stefano a job as a gardener."
Petrucci added: "Now I'll be at the same club as Cristiano Ronaldo. Bloody hell, what a player!"
