"They should make sure that these players stay," said Van Persie, who is reportedly discussing a new deal in North London. "Arsenal have a policy in which they will not go over a specific amount of money when agreeing the salary of a player.
"They won't pay enormous amounts of money. I think that they should go to a higher level of salary.
"If you want to keep the group together, you have to keep them happy. If you are 27 or 28, I can understand that you would make the decision to go elsewhere if you can earn three or four times as much.
"If that sort of money was also paid here, I'm sure that person would stay.
"It is the principle. It is very important that Arsenal keep these guys. This group is unique. If a number of them leave, it will be different.
