Sunday Oliseh conceded a fourth straight defeat in the Dutch Eerste Divisie as Fortuna Sittard bowed to a 2-0 loss against AZ II.
Fortuna are yet to win a league game since their 2-1 win over Ajax II on January 12 and have only scored a goal with nine conceded in their last four league outings.
Second half goals from Owen Wijndal and Ferdy Druijf propelled the hosts to a comfortable win at the AFAS Trainingscomplex on Monday night to extend Fortuna awful run to four losses in a row, following defeats against Dordrecht, Emmen and Volendam.
Prior to the poor run of results, the former Borussia Dortmund and Ajax midfielder led the Fortuna Stadion outfit to their first silverware in 23 years in January after finishing as winners of the second period in the Eerste Divisie.
Oliseh will be aiming to bounce back from the setback when Fortuna host fifth-placed Telstar in their next league outing on Friday.
They are placed third in the Eerste Divisie table with 44 points from 24 games – five points behind league leaders, NEC Nijmegen.
