Denis Cheryshev and Casemiro will both reportedly be part of Real Madrid's first-team squad for the 2015-16 season.
Cheryshev, 24, has been on the books of Real Madrid since 2002, but has not yet made a single first-team appearance for the capital outfit.
The Russian, however, has been in fine form on loan at Villarreal this season, while he spent a section of the 2013-14 campaign on loan with Sevilla.
Casemiro, meanwhile, has made 27 appearances for Real Madrid's first team, but was sent on loan to Porto last summer, where he has thrived this season.
According to Inside Spanish Football, Real Madrid boss Carlo Ancelotti has been encouraged by the pair's development and will welcome them back to the Bernabeu for the new campaign.
Neither Villarreal nor Porto have the option to sign either player at the end of the season without entering into a fresh agreement with Real Madrid.
