He began in the youth ranks of Argentine club San Lorenzo and his professional debut came in 2002. In 2006, he moved to Mexican side Monarcas Morelia. He was a fixture in the starting line-up for the Mexican club. He returned to San Lorenzo in 2007, but did not find regularity with the first team, only playing six games.
In 2008, he was sold to Universidad de Chile for $1 million and signed a five-year contract with the club. At the time the price tag was the most ever paid by a Chilean club. However, since the move, Colo-Colo paid $1.2 million for Domingo Salcedo and then paid $2.2 for Macnelly Torres.
Universidad de Chile
Actuating at Universidad de Chile, after a poor beginning, he started becoming a notorious player, as well as one of the La U's most respectable ones, considered by the manager Sergio Markarián itself the one who usually commanded the moves in the team. In the Copa Libertadores 2010, he obtained visibility in Brazil, after good appearances in the matches against Flamengo, doing even a beautiful coverage goal in the second match.
Although losing it, they won over Flamengo by away goal. During the competition, Montillo dedicated his goals to his newborn baby Santino, who has down syndrome; he grew visibly emotional after the crowd then chanted in support of Santino.
During the campaign in La U into Libertadores, Montillo became harassed in many Brazilian teams, including Flamengo and Vasco da Gama, but the one who really did get the Argentinean midfielder was Cruzeiro; even though his contract renew with Universidad de Chile until 2014, after rejecting the Flamengo's offer. His hiring at the Celeste squad was announced in July 2 by US$3.5 million, and he joined the club after Universidad de Chile finished playing the Copa Libertadores, which the team left in the semifinals.
On 15 August, he made his debut against São Paulo FC, in a 2-2 away draw, making an assist to the 83rd-minute goal by Thiago Ribeiro. Montillo scored his first goal against Corinthians in a 1-0 win in the 3rd minute, match that took in place in Uberlândia. Besides conducting the team's midfield, he showed himself as a scorer as never did before — in 15 matches, he scored 7 times, beating his total score at San Lorenzo, which he considered the best moment in its career —. With Montillo, the squad's avail increased from 50% to 62%.
In 2010's December 5, after Cruzeiro get the runner-up in the Brazilian League, montillo was laureate with the Armando Nogueira Trophy as the best player in the competition. In the following day, he got the Placar's Bola de Prata as one of the best midfielders of the League, receiving it from the hands of Sorín — an oldschool idol in Cruzeiro.
In 2011, at the first match in the Copa Libertadores done by Cruzeiro in the year, Montillo scored twice, as well as giving assistance in the rout over the Argentinean Estudiantes by 5-0 — in a beautiful spectacle that had a special taste for Cruzeiro, once their last match was played their elimination at the 2009 Copa Libertadores by 1-2 at the Mineirão —. Wondrously, the Celeste squad was eliminated at the round of, against Colombian Once Caldas, a fact that shocked supporters and the South America's media.
In the Brazilian league, after being criticized along the entire Cruzeiro squad, which began very poorly the championship, Montillo recovered its football with the arrising of the manager Joel Santana. He did the two goals of the victory over Grêmio by the 8th round, in July 6, getting the best scorer position in the league for a few rounds. Diverging among the bad Cruzeiro appearance in the Brazilian League in that year, Montillo then won his second Bola de Prata followed by the title as one of the best midfielders in the league again. In 2011, he was the Argentinean midfielder who most scored in all the world.
In 2012's 25 February, Montillo became Cruzeiro's biggest foreign scorrer of all time since 1942 — when the team left its old name Palestra Itália —, after scoring twice against Democrata, reaching the mark of 30 goals, beating Víctor Aristizábal, which scored 28 times with the Celeste uniform. In March, the player renewed its contract to actuate in Cruzeiro until the end of 2015. Cruzeiro's president Gilvan Tavares increased the termination fine to €80 million, making Montillo the most expensive player in the South America.
On 3 January 2013, through Twitter, Santos announced Montillo as their player for next season. Despite the undisclosed negotiation, it is thought that Montillo was bought for R$16 million. Montillo must wear shirt number 10, that was worn until 2012 by Paulo Henrique Ganso. The coach of club, Muricy Ramalho, praised his coming. The player made his debut wearing the shirt of Peixe on January 16, 2013, when the club won Grêmio Barueri for 4-0. Montillo approved the victory and his partnership with Neymar, who he praised.
He played for Argentina U20 in the 2003 FIFA World Youth Championship in United Arab Emirates. He played in most of the team's games. Recently, he was called by Alejandro Sabella to play the second match of the mini-tournament "Superclássico das Américas" against Brazil, where only players who were playing in South America could be called, woring the number 7. Although the loss by 2-0, Montillo was very praised by the Argentinean media. He was called again to represent Argentina in the friendly match against Sweden on 6 February 2013, but he remained on the bench the 90 minutes.
He made his first full appearance for the national team against Venezuela in a World Cup qualification match on the 22nd March 2013. His acting in this game was praised by coach of Santos, Montillo's club, Muricy Ramalho. According to Ramalho, the Argentinian "was very well. He is improving step by step." On 7 June 2013 against Colombia he was one of the starting eleven, substituting the injured Lionel Messi.
