He is a former Paraguay U20 international.
West Ham United loan
He joined West Ham on 29 August 2011 where he signed a season-long loan contract saying, "I am very excited to come here and play in England, I am hoping to get a chance to show the fans what I can do." Montenegro's first and only appearance for the senior squad was as a 78th-minute substitute on 8 January 2012 in a 1–0 FA Cup third round away defeat to Sheffield Wednesday. At the end of the season, a new contract was not agreed and he returned to Paraguay.
Rubio Ñú and Libertad
In 2013, he joined Paraguayan Primera División side Rubio Ñú where he scored three goals in 14 games. His form earned him a move to fellow Paraguayan Primera División side Club Libertad. During the 2013/14 season he scored nine goals in 36 games.
In July 2014, Montenegro signed with Primera División Paraguaya Club Nacional Asunción to participate in the semi-final stages of the 2014 Copa Libertadores and the Torneo Clasura of the Paraguayan Championship.
Replacing injured forward Fredy Bareiro, Montenegro was in the starting line-up of the first-leg of Nacional's semi-final Copa Libertadores fixture against Defensor Sporting on 22 July. In the 35th minute of the first-half, Montenegro opened the scoring for Nacional, giving them a 1–0 lead, the goal was assisted by Julián Benítez. The fixture concluded 2–0 in favor of Nacional.
Loan to Leeds United
On 25 October 2014, Montenegro was named in Leeds' matchday squad for the first time when he was named as a substitute against Wolverhampton Wanderers. He made his debut in the same match as a 2nd half substitute in a 2-1 loss. The match was the last game for Head Coach Darko Milanič who was relieved of his duties minutes after the game.
After scoring an impressive 15 goals in 17 league games during the 2016 Primera Division Paraguaya season for Nacional Asuncion, Montenegro was loaned to Cerro Porteño for the remainder of their 2016 Copa Libertadores campaign. Several days later however, the transfer was declined due to a documentation requirement.
Montenegro has played for Paraguay's Under-20 side and featured in the 2011 South American Youth Championship in January 2011. He also played at the 2013 FIFA U-20 World Cup in Turkey, where he scored with an "acrobatic overhead kick" against Greece in the group stage.
