The Dons are currently just a point outside the top six after a testing start to life under Robinson and the 30-year-old admits he may have to change things around after Christmas.
He told Press Association Sport: "It`s been a fantastic start for us.
"If you look at the injuries we`ve had to carry and the way the budgets have gone across the leagues we have done well.
"Brighton and Swindon have spent a bit this year and there are your Southamptons and Plymouths and Huddersfields - it`s a tough division out there.
"There are nine or 10 teams up there with bigger budgets than us but it`s not all about the money. Once that whistle goes it`s irrelevant how much you earn, I have a squad of players which I am trying to mould. If that goes well then great, if they can`t adapt then maybe I will have to make changes after Christmas but that is all part of my job."
