When asked if he will not be leaving before then, Holland replied: "That's the situation as I understand it."
Meanwhile, Holland was happy to see Marco van Ginkel feature in the win over Wimbledon as the Dutch midfielder continues to build up his match fitness after being sidelined since last September with a knee injury.
He added: "Marco has worked fantastically hard to come back from an awful injury at Swindon and has had a long road back but he has done magnificently well, well enough to be involved in the Dutch squad's training just before the World Cup.
"He is accumulating games and he is looking stronger every game, and it is really important he gets a good pre-season."
Holland continued: "It is early days for the squad. We are still using 21 players over the two halves and the second-half team did better than the first-half team did this time, but it was still an opportunity to see a lot of the players we don't usually get to see at this time of year. The good thing about this game is that the lads kept going and showed good spirit to recover the game.
"On Monday we get the Spanish players, Gary Cahill and Filipe Luis into the squad and slowly it will take shape as the weeks go on."
