Ajax have moved five points clear at the top of the Eredivisie table after beating title rivals PSV Eindhoven 3-2 at the Philips Stadion.
The Amsterdam outfit broke the deadlock on the half-hour mark courtesy of Kolbeinn Sigthorsson, but the hosts hit back in first-half stoppage time through Jeremain Lens.
Christian Eriksen's ninth goal of the season put Ajax back in front seven minutes after the break.
Lens equalised again on 69 minutes, but Derk Boerrigter struck the winning goal eight minutes later to send the visiting supporters into raptures.
PSV now sit third, six points off the pace with four games remaining.
