Eredivisie leaders PSV Eindhoven held firm to beat NEC Nijmegen 3-2 at the Philips Stadium and book their place in the semi-finals of the KNVB Beker. Dries Mertens put the home side in front in the fifth minute, but Nick van der Velden\'s 15th-minute equaliser gave the visitors hope of an upset. Tim Matavz and Kevin Strootman put the hosts in the driving seat before half-time and, although Lasse Schone narrowed the deficit, NEC were not able to find an equaliser.
