Real Madrid goalkeeper Keylor Navas has revealed how he was sometimes forced to take injections to enable him to get through matches last season.
Navas had an outstanding campaign for Los Blancos before undergoing surgery on a long-term tendonitis problem in his heel rather than play for Costa Rica at the Copa America.
"In the end I got used to the pain, and it seemed it was not so much," the Costa Rican keeper told Marca.
"I was controlling it, although I played with a lot of pain. When we did the tests you could see the decision [to operate before the Copa America] was the best for my health.
"It was a difficult year, I got used to the pain, although it is the not the recommended thing to do. Once the season was over, the problem had to be stopped at the root.
"You always want to play, although when I did not play it was because I was honest and said I could not. There were moments in which I needed a rest to be able to be stronger for the following game."
