I agree, Real Madrid should have spent this transfer window much more active. If they want to be champions, they must play without making any mistakes and have no problem scoring goals.
Right now they have started the league well and have not lost points but the other teams have not yet reached their potential to play at their best. Considering that it was a league where competition continued until the last few weeks, teams with few or not enough star players may start to lose points in the following weeks of the season
Real Madrid did the best they could do in the last transfer window even though their may not have been the club that spent the highest money in signing new players but then also the club did not let go too much of their players since they had already invested a lot of money on those players in the previous season and this has reflected in the result Real Madrid recorded in the last two seasons.
Even though the just-concluded season was filled with a lot of setbacks for Real Madrid, they still managed to secure second in La Liga coming and following close to Barcelona in the last season's title rankings.
