Indeed the side from Vallecas have been in decent form at their uniquely compact stadium (which only has three stands and just advertising hoardings behind one goal), with only Real Madrid and Barcelona able to win there so far.
Paddy Power price another victory for Rayo this evening at 6/5 (2.25) while Zaragoza can be backed at 12/5 (3.40) and the draw is offered at 11/5 (3.20).
Yet the bet for matches involving Rayo this season has been over 2.5 goals and a repeat this evening looks tempting at 8/11 (1.73).
Paco Jemez's side look decent going forward and in Leo Baptistao they possess a youngster with exceptional talent.
The Brazilian has already got six goals this season and is developing into one of La Liga's most exciting prospects; he is available at 2/1 (3.00) to score at any time and that has got to be worth some consideration for a value bet.
Despite their potency in attack, at the back Rayo have also produced some extraordinarily inept defending this season, and have managed just one clean sheet in their last 11 games.
Matches involving Rayo this campaign have been the fourth most high scoring in the division averaging 3.43 goals a game.
While Zaragoza's games have not seen quite as many strikes, their encounters still average 2.79 goals a game making over 2.5 goals this evening an extremely attractive option.
This bet has already paid out nine times in the league this season in games involving Rayo - as well as in six of the last seven meetings between these two teams in all competitions, which further strengthens the credibility of the selection and makes the price of 8/11 (1.73) look like very good value.
