The midfielder has recovered from knee surgery and is now training with the Osasuna first team squad.
"It's natural that after six months I won't be ready immediately, but I am doing everything I can to get myself at everyone else's level. I cannot say when I will reappear, but I know that I will certainly play this season," he said.
"The rehab was very difficult. I collapsed a thousand times and I could not believe that my colleagues were playing and I was on a bed."
