The 31-year-old winger was diagnosed with testicular cancer 15 months ago but, having made a full recovery and featured on several occasions for Newcastle's under-21 team, he is dreaming of a day he thought he would never come - a return to St James' Park.
And if that happens, the feeling would surpass even his selection for the 2010 World Cup, where he made three appearances for Argentina under coach Diego Maradona.
Jonas Gutierrez: "I have played in a World Cup but if I play again for Newcastle then that will be the best moment of my career.
"To get back after the cancer and chemotherapy, to put all that behind me, would be a huge moment. I feel really good. Maybe in two weeks I will be at 100 per cent.
"The welcome from the fans from the day I arrived has been special. So if I come back and play for Newcastle then, of course, it will be the best. It will be emotional.
"I haven't been to the stadium. It is hard to go and not be involved. For now, I prefer to watch on TV at home. But, of course, I want to return to the first team.
"When I was told about the cancer I went home to my dad and cried. Then it was hard to find my hair falling out.
"But I was always positive and I told my family and friends, 'Listen, the most important thing is to be healthy again'. Fighting cancer made other problems seem insignificant."
