Al Nassr are convinced that Cristiano Ronaldo will end his career with the Saudi Pro League side and have not ruled out extending the striker's mammoth contract, sources told ESPN.

Ronaldo made his first appearance for Al Nassr in a 1-0 win over Ettifaq on Sunday. He signed a two-and-a-half-year deal with the Riyadh-based side worth $200 million per year following his departure from Manchester United in December.

The Portuguese star will be 40 when his deal ends in 2025, and Al Nassr officials believe it is unlikely that he will play somewhere else before hanging up his boots. Sources have told ESPN that Al Nassr have not ruled out extending Ronaldo's contract if he wants to continue his playing career.
