"The official event for the renewal of Cristiano Ronaldo's contract will take place tomorrow, Monday 7 November at 1:30pm in the presidential box at the Santiago Bernabeu stadium," Madrid said in a statement yesterday.
"The Portuguese forward will extend his contract until 30 June 2021 at the event attended by club president Florentino Perez and the player himself."
Ronaldo, 31, follows in the footsteps of Gareth Bale, Luka Modric and Toni Kroos as the latest Real star to agree a contract extension in recent weeks as the club prepares to serve a one-year transfer ban imposed by FIFA.
However, Ronaldo, whose previous deal expired in 2018 is expected to remain the highest earner at the Santiago Bernabeu.
