The 19-year-old was expected to join United, before PSG confirmed the big-money signing of the youngster on Wednesday.
“Everything was agreed between Sao Paulo and Manchester United,” Moura’s agent Wagner Ribeiro told UOL.
“The contract had been written and just needed to be signed. But then Leonardo called me and asked to talk to Lucas.
“They talked. Leonardo was helped by the fact he is Brazilian. He was very gentle with Lucas.
“The possibility of living in Paris – a much more pleasant city than Manchester – also influenced his decision. But it was PSG’s project that impressed Lucas.”
“I’m just a worker,” he added. “I’ve not been able to sleep for five days here in Europe. I can’t rest and I miss my son.
“I boarded a plane at 5am in Manchester and arrived in Paris this morning to finalise everything with Leonardo.
“But what gives me the taste of victory is that I know Lucas is happy.”
