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.
