Rayo were the best home team in Europe last season until the half of the season. It is partly explained by the fixture list, but it can not be overlooked that they were better home team than anyone else, as a promoted team!

This season they have played 7 home games with a 4-2-1 saldo, scored 12 goals, and won at home among others Valencia and Real Madrid.

Now they also a secret weapon at disposal as Raul de Tomas is finally allowed to play after his signing after some controversial actions, and there has probably never been a more goal-hungry player as he has been without a game for months even if he has been fit.

After the break, they got a 2-2 draw at Girona, and got kicked out of the cup away at Gijon, but back at Vallecas they are ready to give another dominant attacking performance. Thinking about that they have also Falcao and De Tomas they still probably start with Camello upfront, the squad has no injury or suspension worries, or cup fixtures any more.

Betis of course are a team with more resources and name, but they are not a specially good team on the road as they have won only 2 of their 7 away games. and they have been stopped by weaker clubs like Valladolid, Celta, and even the extremely weak and goal-shy Cadiz side.

More than that, they still have the Spanish cup going on, they will travel to Saudi-Arabia to face Barcelona in the Spanish Sper cup, and they are suffering from the suspension of Luiz Felipe and a few injuries to less important players. Some of the players like Alex Moreno are still considering a move to a better and richer club, like Unai Emery's Aston Villa.

Given that Vallecano would be leading this at later on 2nd half I believe in their will and attacking class to score another goal, probably by De Tomas, and Betis just have too much on their mind at the moment to be able to give the fighting spirit they would need at Vallecas.

拉约是上赛季欧洲最好的主场球队，直到半个赛季结束。这在一定程度上可以用赛程表来解释，但不可忽视的是，作为一支升班马，他们是比其他任何球队都更好的主场球队!

本赛季他们用4-2-1阵型打了7场主场比赛，打进12球，并在瓦伦西亚和皇家马德里等球队的主场获胜。

现在他们还有一个秘密武器，劳尔·德·托马斯在经过一些有争议的举动后，终于被允许上场比赛，而且可能从来没有一个球员比他更渴望进球，因为他已经几个月没有比赛了，即使他已经恢复了健康。

在中场休息后，他们2-2战平赫罗纳，并在客场被希洪踢出了杯赛，但回到巴列卡斯，他们准备再次表现出统治性的进攻。考虑到他们还有法尔考和德托马斯，他们仍然有可能让卡梅洛首发，阵容没有伤病或停赛的担忧，也没有杯赛的赛程。

贝蒂斯当然是一支拥有更多资源和名气的球队，但他们并不是一支在客场表现特别好的球队，因为他们在7场客场比赛中只赢了2场。他们也曾被巴利亚多利德、塞尔塔这样的弱队阻挡过，甚至还有实力极弱且缺乏进球机会的加的斯队。

更重要的是，他们还有西班牙杯，他们将前往沙特阿拉伯，在西班牙斯佩尔杯对阵巴塞罗那，他们正在遭受路易斯·费利佩停赛和一些不太重要的球员受伤的困扰。像亚历克斯·莫雷诺这样的一些球员仍然在考虑转会到更好、更富有的俱乐部，比如乌奈·埃梅里的阿斯顿维拉。

考虑到巴列卡诺将在下半场晚些时候领先，我相信他们的意志和进攻水平会再进一球，可能是德托马斯，贝蒂斯现在有太多的事情要考虑，无法给巴列卡诺提供他们在巴列卡斯需要的战斗精神。
