Ronaldo, 33, is thought to be coming to the tail-end of his career and could leave Real Madrid to pursue one final huge contract when his current deal expires in 2021.
Rumours have been rife that the Portugal international is unhappy with life at the Bernabeu because he will not be offered a lucrative contract to match Barcelona rival Lionel Messi.
And to get one final pay day before he hangs up his boots for good, Ronaldo is said to be considering a move to China.
Former Chelsea boss Scolari spent three years managing Guangzhou Evergrande in the Chinese Super League.
