Pachuca is not the kind of team that we should expect to have won Madrid in that game, even if Madrid were to play with their reserves they would still win that game and it was of of their chances o having a trophy this season so messing it was something they were never going to do, anyways congratulations to Madrid for their first trophy for this season hopefully they win another one before the end of the season.
You are right because even if Real Madrid entered the second string of players in that game Real Madrid could still win the game and maybe Ancelotti didn't do that because he respects every game even though it's not a trophy to be proud of. Real Madrid are always serious about facing any team and I respect their coach because even though they are facing a much weaker opponent they still fielded their squad as usual even though there were some changes. This is the first trophy of the season and hopefully there will be other trophies that Real Madrid will get this season, either La Liga or the Champions League.
Real Madrid won this important match to secure the trophy so we say the trophy of this tournament is not very important but if Real Madrid had not won this match think about how much criticism would have been given to Real Madrid. I think those who will field as opponents are all strong and should respect all of them and consider strong and field accordingly. If a team takes an opponent lightly, it can be seen that the stronger team is defeated by the weaker opponent. Real Madrid is a team that does not want to lose any match and they always want to leave the field with a win in every match. So they don't see it as their opposing team is weak rather they think every team is much stronger and accordingly they declare the team and every player of the team always try to play with their maximum.
