Tuhia he haere tonu mo tenei irava - I hainatia a Prost ki te whakauru ki a Ferrari i te tau 1990, ka waiho hei kaihauturu tuatahi i hainatia ki te roopu i muri i te matenga o te kaiwhakaara o te roopu a Enzo Ferrari i te tau 1988. I whakakapihia e ia a Gerhard Berger i Ferrari, a, i whakahoahoahia e te Piriti a Nigel Mansell mo (Berger i noho ki te nohoanga o Prost i McLaren). I te mea ko ia te toa o te ao, ka riro a Prost hei kaihauturu matua mo te tiima, ana i kiia ko ia te kaitakaro i runga i tenei mana. Kei te maumahara a Mansell ki tetahi huihuinga i te 1990 British Grand Prix, kaore te motuka i taraiwa e ia i te rite ki te whakataetae o mua i riro ai ia i te tuunga tuunga, ana i muri mai ka kitea mai i nga miihini o te tiima i kite a Prost i a Mansell he motuka pai ake ana ka whakawhitihia e ia me te kore e mohio a Mansell. I wikitoria a Prost i ngā whakataetae e rima mō Ferrari i tērā tau, i Brazil, i Mexico
, France, Ingarangi me Spain. Ko te mea nui i roto i enei ko te Mexican Grand Prix, i wikitoria ia i muri i tana tiimata i te tuunga 13. I nga whakataetae Mexico me Paniora, i arahi ia i a Mansell ki te Ferrari 1 × 2 mutunga. I tae ano te whakataetae ki te rauna whakamutunga o te wa i Japan me Prost e whai ana i tana hoa whawhai McLaren, Ayrton Senna, e iwa nga tohu. Pēnei i te tau 1989, he tūtukitanga tautohetohe i waenganui i te tokorua i whakatau i te whakataetae. I te kokonga tuatahi, i whakaae a Senna i te tau i muri mai, i peia e ia tana motuka whakataetae ki a Prost, i tangohia ai e raua tokorua i te whakataetae me te hiri i te taitara ki a ia. "He mea whakarihariha tana mahi", i mea a Prost. "He tangata kore utu ia". I mutu a Prost i te wa e whitu nga tohu i muri i a Senna, a ko tana roopu Ferrari te tuarua ki a McLaren.
