Granada should be the favorite here.

Rayo Vallecano is a newly promoted team and one of the weaker squads in La Liga. The lack of quality is huge as they were promoted in the playoffs, suffering a lot and didn't make any good transfers to raise the level of the team.

Lost the first two games played, but it's also true that their rivals were pretty strong: Real Sociedad and Sevilla. Anyway, they don't have enough level for this category in the defence and attack, where players are so weak. They don't have any good strikers and either central backs with quality.

On the other hand, Granada changed the coach but continued with the same project and ambition. Their last seasons have been amazing, even qualifying for UEL when they were newly promoted, and definitely is one of the hardest teams to beat in La Liga.

They made a good transfer market, as main players stayed in the team while also made good signings like the striker Bacca. In the first two rounds they played against strong teams like Villarreal and Valencia, achieving a draw in both games.

Only reason to see these odds here is the fact that it will be the first match at home for Rayo, which could mean a bit more motivation. But nothing else.

Quality and especially experience are on the away side, which are the favorite to achieve the victory here in my opinion. The double chance looks safe for me.

格拉纳达应该是最受欢迎的。

巴列卡诺是一支新升级的球队，也是西甲实力较弱的球队之一。质量的缺乏是巨大的，因为他们在季后赛被提升，遭受了很多，没有做任何好的转会来提高球队的水平。

前两场比赛都输了，但他们的对手也相当强大:皇家社会和塞维利亚。无论如何，他们在防守和进攻方面没有足够的水平，球员们都很弱。他们没有一个好的前锋，也没有一个有实力的中后卫。

另一方面，格拉纳达更换了教练，但仍然保持着同样的计划和雄心。他们上个赛季的表现令人惊叹，甚至在他们刚刚升级时就获得了进入UEL的资格，这无疑是西甲最难击败的球队之一。

他们创造了一个良好的转会市场，主要球员留在了球队，同时也签下了像巴卡这样的好球员。在前两轮比赛中，他们与比利亚雷亚尔和瓦伦西亚等强队交手，两场比赛都打成平局。

唯一能看到这种可能性的原因是，这将是拉约的第一场主场比赛，这意味着更多的动力。但是什么都没有。

质量和经验是客场的优势，在我看来，客场是赢得胜利的最有利条件。对我来说，双重机会是安全的。
