Sabella's side now face Germany in a bid for a third World Cup victory after beating Netherlands 4-2 in the penalty shoot-out after 120 goalless minutes, and the Argentina Coach said: "We could do with a couple more days to rest, but what is important is that we made it to the final. Let's see how we handle it."
The final will be the third time the pair have faced each other in Brazil, and the history of the two in the World Cup has seen them meet twice before in the final down the years. Argentina took part in the first ever World Cup final back in 1930, where on that occasion they were pegged back by Uruguay 4-2 having lead by three goals at one stage.
The South Americans have since won the World Cup twice, the first being an extra-time victory against the Netherlands in 1978 helped by Mario Kempes scoring a brace along the way. A second crown came eight years later in 1986, as Diego Maradona's brilliance lead Argentina to victory after a 3-2 triumph over West Germany in the final.
This was the first of two consecutive finals contested between Argentina and Germany, and the Germans exacted revenge to win the 1990 World Cup with a 1-0 victory thanks to a late penalty from Andreas Brehme.
Three-time winners Germany dismantled hosts Brazil 7-1 in the 2014 semi-finals, while Argentina had to survive a penalty shoot-out against the Netherlands which was sealed by Maxi Rodriguez after Goalkeeper Sergio Romero saved penalties from Ron Vlaar and Wesley Sneijder.
Sergio Aguero returned and scored one of the winning penalties in that shoot-out victory, and the Manchester City striker said: "A lot of people didn't think Argentina would get to the final but we knew what players we had, very good players individually. This means so much."
The winning penalty was scored by Rodriguez, who added: "We know the pain we have been through, and we deserved some kind of happiness. Now we have to play the final but that is what we have dreamed of ever since we left Buenos Aires. We must make the most of it and let's hope that the last 90 minutes are on our side."
Argentina enter at 5/2 to win with Bet365, while Lionel Messi is 5/1 to score first with Betfair. No injury concerns have been stated by either side in regards to the final, although Argentina's coach admitted that the recovery time is much needed after his side's extra-time victory on Wednesday.
Germany and Argentina kick off the final in Rio de Janeiro at 8pm Sunday 13 July, and the match will be shown live on both BBC1 and ITV. You can compare all the odds for the 2014 World Cup right here.
