Rangers manager Mark Warburton has stressed to Talksport the importance of getting the balance right when it comes to bringing in new faces.
The Light Blues secured their promotion to the Premiership a fortnight ago, but Warburton said the club's transfer plans were already underway.
Accrington pair Matt Crooks and Josh Windass have already agreed moves to Ibrox this summer, but the 53-year-old has targeted another "four or five" additions with the possibility of more should Rangers secure Europa League qualification via the Scottish Cup.
Warburton is keen to blend youth and experience next term, and has put his faith in head of recruitment Frank McParland - a man he describes as one of the best in the business - to deliver.
"The recruitment will be key for us next year. If we are going to close that gap (on Celtic) we’re going to have to get the recruitment right," Warburton told Talksport's Drive show on Monday.
"(Rangers need) to get that bit right and make sure that the four or five - if we go into Europe, six possibly - that we need to bring in are the right types and get the right balance as well.
"We need some experience, we need some physicality, but at the same time we’re about young hungry players who can hope to play the game at the right tempo and intensity.
"Getting that balance right, getting the right characters in is not an easy task that’s for sure, but in Frank McParland we have one of the best in the business. I’ve got every faith that we’ll be successful in that area."
McParland, the former Liverpool chief scout, left Burnley in favour of a move north of the border in October, reuniting with Warburton after spells together at Watford and Brentford.
As well as identifying Crooks and Windass, McParland oversaw the January additions of Harry Forrester, Maciej Gostomski and Michael O'Halloran, along with the loan capture of Hearts' Billy King.
