Porto was another European club eliminated. I guess the players thought enough is enough, let's go on vacation. Otherwise they wouldn't have conceded 4 goals against a team like Al-Ahly. Even if they had won, nothing would have changed because Inter Miami was leading 2-0 then conceded two goals in the last 10 minutes to draw the match and Inter Miami and Palmeiras advanced to the next round.
Atletico Madrid and Porto were the teams eliminated early. But this shouldn't come as a surprise. Not every player gives this tournament the same importance. You have to give credit to the players after a long league marathon. They need a vacation, they need to rest. Otherwise they are more likely to get injured.
Atletico Madrid were indeed very unlucky for not making it to the next round,there elimination came as a surprise to me because after winning Botafogo by 1-0,they were still eliminated and Botafogo qualified. Lucky Botafogo made it to the round of 16, it wasn't easy for them to be among the qualified clubs that made it to the next phase. Brazilian clubs are quite amazing in this CWC,to be honest I didn't expect to see Brazilian clubs playing this good, infact I am satisfied with their performance in the group stages,hope they will continue to keep it up now that they have made it to the round of 16.
Atletico Madrid despite playing well, could not achieve the desired goal. They only scored one goal at the end of the match to get three points but they should have won by a greater margin to go to the next round. It was perhaps beyond imagination that the Brazilian club Botafogo would play so well qualify for the second position. In the first match of the group stage of the tournament, they lost 4-0 to PSG so Atletico Madrid should have won by a greater margin but even though the team players played aggressively the Brazilian club Botafogo played defensively and Atletico failed in every attack. The equation of the group stage was set in such a way that even if the three teams in the group had 6 points, Atletico Madrid had to leave the group stage. Another reason for this is that PSG had lost 1-0 to Botafogo in the previous match.
