Real Madrid will also lose games and draw some because this is how it used to be every season, so I don't think these two points that Barcelona lost will cause them any problems because they have only played three of the 38 La Liga games.
Well, Real Madrid had a brilliant display against their opponents, Mallorca during the weekend. Let's just assume they were able to utilize all the chances they had, it would have been a different story -- cause the goals count as well, don't forget!
It's a good start for them this season, they failed to maintain their consistency during the middle of the league in the previous season, finishing the league without the trophy. Xabi Alonso is just trying to adapt to the league -- trust me, if Hansi tries anything funny, they might be a serious overtaking this season.
