NAC Breda coach Mitchell van der Gaag admits they're seeking more additions from Premier League partners Manchester City.
City have already placed goalkeeper Arijanet Muric, defender Erik Palmer-Brown and midfielders Luka Ilic and Paolo Fernandes on-loan at NAC for the new season.
Van der Gaag stated: "We are working on a number of players, I hope it will be completed soon.
"There'll be two to three from City, but we will not focus on City alone, that would not be good."
Van der Gaag has stepped in this summer to take charge after Stijn Vreven's departure.
