On-loan to June, Juve may struggle to buy Morata outright this summer. He permanent option is set at €45m.
The Spain international said: “Everyone knows that I would stay here for life, but football is a business and sometimes footballers don't have the choice.
"I am a professional and I will give it my all until I am here, where I am very happy."
Juve can still extend Morata's loan for another season for a fee of €10m.
