Colombia take on Greece in the opening game of Group C in the Estadio Mineirao, Belo Horizonte, in the first of Saturday's World Cup matches.
In what is a wide-open group, it is vital to both that they don't taste defeat. Colombia have failed to make it past the group stage in their four previous campaigns while Greece have never progressed to the knockout stage.
Colombia are still adjusting to life without the players they lost before the World Cup even started. Radamel Falcao, Edwin Valencia, Luis Perea and Aldo Ramirez were all unable to join the 23-man squad due to injury.
Inter Milan's Fredy Guarin is suspended for Saturday's game, and coach Jose Pekerman has to decide which of his strikers starts the game against Greece.
Sevilla's Carlos Bacca, Teofilo Gutierrez of River Plate and FC Porto's highly rated forward Jackson Martinez are all battling for one place—unless Pekerman decides to change the formation.
Greece coach Fernando Santos has two big injury worries for Saturday. Defender Sokratis Papastathopoulos missed two of the friendlies with a muscle problem and will be assessed, as will striker Kostas Mitroglou, who is recovering from a knee injury.
We'll be rating the performance of the players on both sides at half-time and full-time, so be sure to check back here to how each player is doing.
The match kicks off at 5 p.m. BST (12 p.m. ET)
Ospina - Great save on Kone's shot. There when it counted.
Zuniga - Active more in the second half. Kept Holebas back in his own half.
Zapata - Has done well to stop the Greek attack. Solid performance.
Yepes - Legendary performance from the veteran defender. Earned his clean sheet.
Armero - Great goal, getting down the wing well, wonderful energy.
Sanchez - One of Colombia's best players. Commanding performance.
Aguilar - Passing has been neat and tidy, impressive display in the heart of the midfield.
Cuadrado - Lovely skill on the wing for two of Colombia's goals. Dangerous at all times.
James - Great dummy for the ball. Always eager to get on the ball. Deserved his goal in the end.
Ibarbo - Good energy and strength down the left. Quiet second half.
Gutierrez - Took his goal well. Led the line well. Good display in the opening game.
Mejia - Didn't do much on the ball. Didn't have to.
Arias - Came on to protect the right side of the defence and did well enough.
Martinez - No real chance to show what he is capable of.
Karnezis - Couldn't do anything for the goal. Didn't have much chance with the goals.
Torosidis - Gave too much space to Cuadrado for the goal, was easily beaten. Much better in the second half.
Sokratis - Will be disappointed to concede three goals. Not a lot of protection from his teammates.
Manolas - Went missing in the defence at times. Will be upset with his performance.
Holebas - Has showed good energy, tried to get forward but asked to defend mostly.
Kone - Greece's best player. Lovely passing, great chance that was saved.
Katsouranis - Quiet game for the veteran midfielder, didn't see enough of the ball.
Maniatis - Busy without really doing anything of note.
Gekas - Came into the game more at the end of the half. Should have scored with a header.
Salpingidis - Very quiet game. Deserved to come off.
Samaras - Best Greek forward. Getting on the ball without really creating any real chances. Had chances that could have made the difference.
Fetfatzidis - Didn't get enough of the ball as Greece would have hoped. Showed some signs of ability.
Mitroglou - Hard work for the forward to get up to the pace of the game and cause any problems.
Karagounis - Came on with the game already over. Not a lot he could do to influence the game.
