If you had watched the Real Madrid vs Osasuna match at Santiago Bernabeu, you would have known that it's not because Real Madrid has a new coach that made them win against Osasuna by 1 goal to nil. In my opinion, Real Madrid struggled to score goals against Osasuna because Real Madrid midfielders weren't creative enough against Osasuna, and even though Real Madrid got used to Xabi Alonso's pattern of play and Real Madrid midfielders continued to perform the way they did against Osasuna, Real Madrid will have problems scoring goals this season.
Many criticisms in the first match were excessive in my opinion, it can't be concluded anything yet but the most important thing now is that Real Madrid managed to get 3 points and I'm sure Alonso knows what to do and he also still needs time to start the process with the Real Madrid team, this is not an easy job but I'm still very optimistic that Alonso's coaching quality can produce results so we just need to be a little patient waiting for the process.
