"I thought I wouldn’t be able to put my boots on and go out on the pitch again. I received a lot of help from people, like Diego Simeone, [Atletico captain] Koke and [president] Miguel Angel Gil, and my psychiatrist," he said on El Partidazo de Cope.
"What you see on TV or social media often is not real and is just an image because it is your job, but often I could not do simple things like lacing up my boots and there were times I went home early because I could not speak and my vision became blurry."
He added: "I didn’t know what was happening to me but it was very complicated and delicate. At that moment you realise that what you like most in the world is what you hate the most, it is complicated."
