Too much expectation won’t make things work out; rather, we should wait and see how it goes. Xabi Alonso won’t disappoint; he will definitely try his possible best to see that Real Madrid succeeds.
So far the games that Real Madrid are playing aren't that hard and Barcelona didn't lose any point. We should wait until the end of September to see Real Madrid facing Atletico Madrid then playing against Villarreal to take more ideas about how good Xabi Alonso managed the team and obviously by the end of October, a clear conclusion will be taken after facing Barcelona. I doubt until then Real Madrid will lose any game.
Frankly, I don’t think these games would be much difficult for Real Madrid, at most their fixture against Villarreal. Atletico Madrid might be something use to be something but, right now, they aren’t that good. Real Madrid isn’t that good either but they can pick up a good challenge. Barcelona is the one team I can say are playing at their best and can easily come from behind to take the lead but at the moment, the race is on between both teams on who gets to drop points.
