Swindon boss Paolo Di Canio wants to add five new players to his squad in time for the start of pre-season training.
Di Canio has recently returned from Italy after having extended his managerial contract with Swindon for a further two years.
"I would like to have all of those players with me for the start of pre-season," he told the club's official website. "That is the target and we have spoken to a number of players already.
"It is obvious that we will have to have more money available because we have gone into League One, but we will not make any crazy decisions. I don't want to break the budget."
