The Spain defender is keen to wear the number 93 on his back in his final year with Los Blancos, as a tribute to his stoppage-time goal that helped the Spanish giants win La Decima in the 2013-14 campaign.
The goal Ramos scored in his club's 4-1 win over city rivals Atletico Madrid in that final is something he holds dear to his heart, which is why he would like make a special tribute to commemorate it.
"Believe me when I say that the thought of changing my jersey number to 93 has crossed my mind," the 30-year-old told Real's official website.
"At the same time, the number four is one that I have always liked and that I have worn throughout all of my time at Real Madrid. It has nearly always brought me good luck.
"But do not rule out seeing me change my number in my final season, as a tribute to what is such a great minute for us.
"The Decima goal stands out above the rest of my goals, given how long we had been waiting to win the Champions League, with it coming in the last minute and because it helped us to go on and become champions."
