Los Blancos have lost two of their first three games of the new La Liga season, but Jese is confident that the capital outfit will overcome a disappointing start.
"The defeat is a shame. We must remain united," the forward wrote on Facebook.
"It's not how you start but how you finish. Support the team and the fans!"
Jese is still on the sidelines recovering from a serious knee injury, but is expected to return to action before the end of the year.
