The Dutchman’s future has been the subject of intense debate after he announced that he would not be extending his contract at the club.
Manchester United have emerged as favourites to sign the 29-year-old but, as exclusively revealed by Goal.com, the player’s agent’s demands could scupper the chances of a move to Old Trafford.
However, Van Gaal says Van Persie will feature for the Gunners this weekend, before joining up with the Netherlands squad for a friendly against Belgium.

“It is a good job, because I almost had not selected him.”
Along with the other Arsenal players who were involved in Euro 2012, Van Persie was granted extended summer leave by the club.
However, the friendly against summer signing Lukas Podolski's former employers Koln completes the Gunners' pre-season preparations, so together with Oranje's match against Belgium it represents Van Persie's last chance of a run-out before the Premier League campaign gets underway.
Van Gaal is hopeful the Dutchman can get some game time against Koln as he feels he is vital to the Netherlands' hopes of success.
“Van Persie is so important for the Dutch team,” he added.
“This is the only time I’ll pick Van Persie and Tottenham’s Rafael van der Vaart while they are not fit."
“They have not played a single game yet for their clubs and normally I don’t pick players then. In future I will only pick fit players."
