The Sevilla man latched onto a superb throughball from Angel Di Maria to run in behind Paraguay's defense and lobbed a delicious chip over goalkeeper Antony Silva.It wasn't a vintage performance from Lionel Scaloni's team but they defended resolutely against La Albirroja's advances. Chances were few and far between at both ends. Sergio Aguero spurned a good chance early on for Argentina while Lionel Messi's goalward free-kick was parried away by Silva.16 games unbeaten 😤Argentina qualify for the Copa America quarterfinals 🇦🇷 pic.twitter.com/16ZPDqWVrP— B/R Football (@brfootball) June 22, 2021Argentina play their last group fixture against Bolivia on Monday, hoping to secure top spot in Group A. Paraguay will take on Chile in their last group stage match.Argentina Player RatingsEmiliano Martinez - 7/10Paraguay didn't really put enough pressure on Emiliano Martinez's goal and the Aston Villa star had a comfortable evening. He only had two easy saves to make in 90 minutes of action.Nahuel Molina - 8/10A terrific performance in defense from Molina. The 23-year-old made some vital blocks and linked well with Di Maria moving forward.Cristian Romero - 8/10Romero put in a massive shift in defense, giving the Paraguayan attackers a serious run for their money. He also made some important clearances in a tight game.German Pezzella - 7/10Pezzela was never afraid to dive into a sliding challenge and was excellent in defence. He also played a key role in helping La Albiceleste regain possession.Nicolas Tagliafico - 6/10An uncharacteristically weak link in Argentina's defense. Tagliafico gave away some ridiculous fouls and struggled to cope with Paraguay's marauding wingers.📸 - It's things like this that Tagliafico is just never going to learn to stop doing. Taking a player down while there was zero danger if he'd let him go, as he was backed up by his teammate. He makes way too many unnecessary fouls. pic.twitter.com/iS10FbF1du— 𝐀𝐅𝐂 𝐀𝐉𝐀𝐗 💎 (@TheEuropeanLad) June 22, 2021Guido Rodriguez - 7/10Argentina's hero against Uruguay was lively once again. Rodriguez was the key on numerous occasions to breaking down Paraguay's attacking plays.Leandro Paredes - 7/10Paredes sprayed the ball in all directions and kept his side moving with some excellent link-up plays.Angel Di Maria - 7.5/10Di Maria cut Paraguay open with a sublime throughball for Gomez to score the opener. He caused the opposition defence plenty of problems all night. The PSG winger completed 88.6% of his passes on the night, providing one key pass and creating one big chance. Di Maria was eventually substituted in the 81st minute.That ball from Di Maria to Papu Gomez though 🤤(🎥: @FOXSoccer)pic.twitter.com/5yAULygmxV— B/R Football (@brfootball) June 22, 2021Lionel Messi - 7.5/10No goals or assists for Argentina's talismanic skipper tonight but he was heavily involved in the build-up to Gomez's strike. Messi also laid a wonderful free-kick late on that was parried away well by the Paraguayan goalkeeper. He also created one big chance, provided a key pass and completed five dribbles during the matchLionel Messi played his 147th international match for Argentina against Paraguay on Tuesday in #CopaAmerica.He is now the joint most-capped player in Argentina's history along with Javier Mascherano 🇦🇷𝐄𝐥𝐢𝐭𝐞 🙌 pic.twitter.com/VL8qFdZTIk— Goal India (@Goal_India) June 22, 2021Alejandro Gomez - 7.5/10The Sevilla man scored the only goal of the night with a lovely chip over the Paraguayan goalkeeper.

Aguero capped off a poor game before getting subbed off at the hour mark.SubstitutesJoaquin Correa - 7/10Correa replaced Aguero in the 59th minute. He got behind the Paraguayan defense more than once with an incredible burst of energy. He helped Argentina see out the game by assisting in defence as well.Rodrigo De Paul - 6/10De Paul came on for Gomez in the 72nd minute. He looked to create chances for Argentina in the dying moments but was constantly hacked down on the flank.Nicolas Dominguez - N/AThe Bologna star came on for Leandro Paredes in the 81st minute. Dominguez didn't see much of the ball after coming on to make any impact in the game.Angel Correa - N/ACorrea replaced Di Maria in the 81st minute.
