Rayo Vallecano coach Paco has urged his players to go and make history by booking a place in next season's Europa League.
Rayo travel to Paco's old club Real Zaragoza, having gone into the weekend seven points off a Europa League slot after three games without a win.
But Paco is well aware of the threat posed by the hosts, who finally ended their dismal run of 14 Primera Liga games without a win when they beat bottom club Real Mallorca last Saturday.
Paco said: ``We are aiming to achieve qualification for Europe, which will be historic for the club, and we must do everything possible not to let it slip through our hands.
``Zaragoza had gone so long without winning, but they have a good team and they are very dangerous because of the position they are in.''
Zaragoza's priceless 3-2 win over Mallorca dragged them to within one point of safety and midfielder Ruben Rochina believes his side's home form during the run-in will prove crucial to their survival prospects.
Rochina said: ``We have a lot of games at home in the run-in and it is all about getting good results with the support of the fans.
``The win last week was good for team morale, but the most important thing is to focus on Sunday because the work is not yet finished.
``We need to go out and give everything for the club and we need the fans to be behind us all the way.``
