Brazil mounted a late comeback to down Colombia 2-1 on matchday four of Copa America 2021.Roberto Firmino and Casemiro scored in the final 20 minutes of the game to cancel out Luis Diaz's early opener for Colombia and continue Brazil's winning run in the competition.Earlier, Los Cafeteros took a shock lead just ten minutes into the game when Diaz converted a perfectly-weighted free-kick from Juan Cuadrado. Just when it seemed like they were headed for a repeat of the 2015 Copa America result when Brazil lost 0-1 to Colombia, Firmino headed home in the 78th minute to restore parity. The goal was contentious, as the ball came off the referee in the build-up, infuriating the Colombian players.Neymar x Casemiro 😤Casemiro's stoppage time goal extends Brazil's winning streak to 10 games 🇧🇷 pic.twitter.com/RQtNIVEaCJ— B/R Football (@brfootball) June 24, 2021After a long check, the goal was allowed to stand. Brazil pushed for the winner, which they found through Casemiro in the 100th minute when the Real Madrid star headed in a Neymar corner.It was a smash-and-grab victory for the holders, who were uncharacteristically poor on the day. But the result confirmed the hosts as Group B winners. On that note, here are the player ratings for both teams:Brazil Player RatingsNeymar inspired Brazil to another victory at Copa America 2021.Weverton - 7/10The Brazil custodian had absolutely no chance with Diaz's effort but was rarely called into action, as his team piled the pressure on Colombia for most of the game.Danilo - 7/10Danilo was a huge attacking threat from the flanks and made a few good crosses too.Marquinhos - 7/10The PSG star marshalled Brazil's backline with aplomb and read the game brilliantly.Thiago Silva - 8/10Brazil's veteran centre-back didn't put a foot wrong in the game. Silva used his wealth of experience to keep Colombia's attackers at bay.Alex Sandro - 7/10He went into the books early on but produced a good attacking performance, driving forward with purpose and stretching Colombia's defence wide.Everton Ribeiro - 6/10The midfielder struggled to exert his influence on the game. Ribeiro was hooked off at half-time to avoid getting sent off, as he had gone into the referee's books for a foul.Casemiro - 8/10Brazil's unlikely hero, Casemiro, popped up with a late, late header to help down Colombia, capping off a decent individual performance.Casemiro wins it in stoppage time for Brazil! ⚽️(🎥: @TUDNUSA)pic.twitter.com/0QEG7cXRlx— B/R Football (@brfootball) June 24, 2021Fred - 7.5/10He was key in regaining possession for Brazil and linked up well with his marauding forwards.Richarlison - 7/10Richarlison made a couple of excellent runs down the middle, which had Colombia on the ropes, but his finishing at times was poor.Gabriel Jesus - 7/10Though never a direct threat, Jesus worked hard to make something happen for Brazil. He missed a good chance at the hour mark when he failed to convert a loose ball.Neymar - 7/10He missed an open chance to score for Brazil, albeit from a tight angle. But Neymar made up for that with a superb corner kick to set up Casemiro for the winner.Neymar roars after Brazil win 🇧🇷 pic.twitter.com/jmQ58WrV0y— Goal (@goal) June 24, 2021Ratings of Brazil's substitutes against Colombia:Renan Lodi - 8/10Lodi set up Firmino for Brazil's equaliser with a lovely cross.Lucas Paqueta - 6/10He attempted an audacious effort from outside the box, which missed the target and was rarely seen in the game otherwise.Everton Soares - 5/10The 25-year old replaced Jesus in the 77th minute but could hardly test Colombia.Roberto Firmino - 7/10Firmino triggered Brazil's comeback with a late headed effort, latching onto Lodi's superb cross from close range.Gabriel Barbosa - 6/10He got on the ball a few times after replacing Richarlison but didn't produce anything of note.
