Real Madrid are said to be hopeful that midfielder Isco will have recovered full fitness for the team's clash with Barcelona on October 28.
The European champions said on Tuesday that the Spain international "has successfully undergone surgery for acute appendicitis," meaning he is set for a stint on the sidelines.
According to Sergio Gomez of AS, there is hope Isco will be back in time for the game against Barcelona, although Madrid play five other matches before then, including Wednesday's La Liga meeting with Sevilla and Saturday's derby showdown with Atletico Madrid.
