Nijmegen, Netherlands – Miralem Sulejmani scored two goals in 0 win at De Goffert Stadion on Sunday.
NEC was able to generate a few decent scoring chances in the first half, but as the two sides entered the second half scoreless, Ajax took charge of the game.
Sulejmani tallied the opening goal in the 53rd minute when a deflected shot from Vurnon Anita fell into his path for a simple finish.
The lead was doubled 12 minutes from time as a corner kick from Theo Janssen fell to NEC's Abdisalam Ibrahim, who turned it over to Sulejmani for his second goal of the match.
Substitute Davy Klaassen put the result away just after entering the match as he found the bottom corner of the net in the 82nd minute to help Ajax keep hold of fourth place.
Third-place Twente was held to a 0-0 draw at home by Vitesse, leaving the club three points clear of Ajax, while Feyenoord moved into fifth with goals from John Guidetti and Jerson Cabral in the final 15 minutes of a 2-1 win over 10- man RKC Waalwijk.
The other match on Sunday saw Den Haag claim a 1-1 draw at Excelsior as Jens Toornstra's second-half goal canceled out an early strike from Leendert van Steensel of Excelsior.
