Anthony Martial admits his Mum helped him make the move to Manchester United.
Martial left Monaco for United in a deal worth a fee rising to €80 million.
He recalled to RMC: "Basically, I was told I was 'untransferable', so I thought only of staying in Monaco.
"When I knew that this offer came, I did not hesitate a second and it was done quickly. I really wanted it and I really wanted to continue to play in the Champions League.
"(Louis) van Gaal called me and spoke to my mother who did the translation. When I arrived in Manchester I met him, we discussed at length and it was done quickly."
