Colombia were impressive in their 3-0 defeat of Poland in their crunch encounter last time out and they've won four of five group stage matches since Brazil 2014, with the exception their opener versus Japan as they played with 10 men following Carlos Sanchez's 3rd minute red card.
Colombia, who overcame the premature exit of injured James Rodriguez, will now play Group G's second-placed side - either England or Belgium - in Moscow on Tuesday, with Japan facing the winners of that group in Rostov-on-Don a day earlier. Japan and Senegal finished tied on almost every tiebreaker, so things had to be decided based on FIFA Fair Play points.
Senegal, who needed only a draw to progress, became the first nation to bow out of a World Cup on the fair play rule.
It meant that, as the full time whistles blew in Samara and Volgograd, Senegal was eliminated due to having accumulated two more yellow cards than Japan.
Africa's last hope of reaching the next round of the 2018 World Cup hit a brick wall on Thursday as its last representative, Senegal was eliminated from the competition.
The group victor will face the runner-up in Group G, which is either Belgium or England.
"Frankly, we were not very good", concluded Cisse, Senegal captain in their run to the quarter-finals in 2002, their only previous appearance at a World Cup.
While the fair-play tiebreaker is far from ideal, it's most likely better than what would have been the case had Senegal and Japan also been tied on yellow cards; FIFA's final tiebreaker, in that case, is drawing lots.
"I don't know if the regulation is cruel or not, but I can't ask my players to go on the pitch in order to avoid yellow cards", coach Aliou Cisse said.
Referee Milorad Mazic pointed to the spot in the 18th minute after Sadio Mane went down in the Colombia area but reversed his decision after a video review showed Davinson Sanchez got the ball in his tackle.
But by the end of an entertaining first half, Pekerman was forced to tinker when Rodriguez was forced off with an injury problem and replaced by Luis Muriel. We can expect a counter-attacking performance from Senegal, similar to the one that brought them victory against Poland.
"Cuadrado understood what Senegal were trying to do, how they were trying to cancel us out", said Pekerman.
