I don't want to think negatively actually, but it seems like PSG underestimated their opponents so their performance was not as full and serious as when they played against Atletico Madrid.
They didn't underestimate Botafogo, we can see that from the PSG line-up. They were just unlucky + Botafogo took the tournament too seriously, maybe this is a way for South American players to get on the radar of big clubs, hope they can be recruited to big European teams. It seems that in this FCWC tournament, clubs from Latin have had more good results, if it continues like this it would not be surprising to see the champion of this tournament be one of the teams from there.
