The goalkeeper is earning comparisons to past greats after his heroics saw Alejandro Sabella's side make their first final or 24 years
The Monaco custodian, who made just three appearances for his club last season, saved spot kicks from Ron Vlaar and Wesley Sneijder on Wednesday to see off Netherlands 4-2 in the shootout.
And before the talk of final opponents Germany begins, Romero says he is planning make the most of the here and now.
"Enjoy this moment," he said. "We will enjoy it and tomorrow we will start working ahead of the final.
"I'm really happy for everything. [Penalties] are a question of luck, that’s the truth. I was confident in myself and fortunately everything turned out."
Romero is already being labelled as a saint in his homeland, earning comparisons to 1990 goalkeeper Sergio Goycochea who stopped two Italian penalties to book Argentina’s last trip to the final, where they also faced Germany.
"We owed this to ourselves," added Maxi Rodriguez.
"This group deserves it. We always come to the quarter-finals and being denied. This time we’ve made it to the end. Let’s keep going."
