Levante continued their fine form in the early Sunday afternoon kick-offs as they won for the fifth time in five tries at midday thanks to Ruben Garcia's goal in a 1-0 success at Real Zaragoza last time out.
The 19-year-old was teed up for only his second senior goal by Michel and those two now seem to have supplanted Juanlu and Nabil El-Zhar in Juan Ignacio Martinez's first-choice XI.
Martinez could have a problem at right-back for the trip to Vallecas as Christian Lell is suspended and Pedro Lopez is still a doubt with an abductor injury.
Levante have now not been beaten by anyone in the league other than Real Madrid and Barcelona for nearly three months and the foundation of their fantastic progress has been their consistency.
By contrast it is impossible to tell whether the free-flowing Rayo will show up or the defensively fragile side that has been on the end of a few hammerings this year.
With both sides though already ahead of schedule in their respective targets for the season, a draw in unlikely to be too disagreeable to either.
