Description:Eredivisie leaders PSV Eindhoven could be knocked off the top of the table on Sunday (March 10) after they slipped up at mid-table Heerenveen. Ajax can go above them if they beat PEC Zwolle, and Dick Advocaat's team have now picked up just seven points from their last five games. They lost 2-1 at Heerenveen on Saturday after a poor first-half in which they conceded twice and never really got going.(1:58)
