Ruiz had been sidelined by injury since Twente's 2-1 defeat to AZ Alkmaar on February 28, but returned for Costa Rica in their 0-0 friendly draw with Argentina on Tuesday. "I recovered in an ideal environment and was able to play 70 minutes for my national team," the 25-year-old said. "I will play lots of minutes against PSV." Twente are just a single point behind PSV with six games to play and Ruiz's return will further boost their ranks with goalkeeper Nikolay Mikhailov set to resume after a groin complaint. Boss Michel Preud'homme will, however, wait on the fitness of Theo Janssen who pulled out of the Holland squad to face Hungary in midweek due to a knee injury. PSV have surged to the top of the table on the back of a run that has seen them lose just once in their past 11 league games. That run has come despite the summer sale of Ibrahim Affelay to Barcelona while Jonathan Reis has been a long-term absentee with injury. While Fred Rutten's side have coped admirably without them they will also be without key striker Ola Toivonen (hamstring) and Danny Koevermans (calf) for their key clash on Saturday night. With the top set to lock horns, third-placed Ajax would have hoped for a quieter week as they attempt to make up some ground at home to Heracles Almelo on Sunday. Instead the club have been headline news for all the wrong reasons after their entire board resigned on Wednesday night following a dispute with club legend Johan Cruyff on how the club should be run. Cruyff returned to Ajax to advise on technical, financial and association issues two months ago but in that time has ruffled the feathers of the club's hierarchy after publicly questioning their ability to help the club return to their past glories. The spat has the potential to derail Ajax's bid to claim a first Eredivisie title since 2004 with the capital club currently six points adrift of PSV. "It's never nice when people like (chairman) Uri Coronel resign as an honorary members. But that's their problem," Cruyff said after hearing of the board's resignation. "Something has to change. That seems clear to me. "If you want to change something, you have some hard decisions." On Saturday, fourth-placed AZ Alkmaar will look to strengthen their Europa League place when they visit Feyenoord while bottom club Willem II will search for just their third win of the season at home to Roda JC. De Graafschap will look to extend a seven-game unbeaten home run against NAC Breda and Heerenveen host relegation-threatened Excelsior. On Sunday, Europa League hopefuls FC Utrecht and ADO Den Haag meet at Stadion Galgenwaard, Vitesse Arnhem entertain NEC Nijmegen while FC Groningen are at home to second-from-bottom VVV Venlo.
