Spain has two direct places in the CL, and two places in the qualifying series. The winner of the CL-final is certain of a direct spot for next year's CL. So the winner of La Liga and the winner of the CL have a direct place in the CL. That leaves the places 2&3 for playing qualifying-matches.
IF WE DON'T WIN LA LIGA WE WILL HAVE TO PLAY CL-QUALIFYING-MATCHES!!!!!
