Mark Warburton's men appear well on course for promotion from the Scottish Championship.
Rangers legend Andy Goram has urged Dave King to get ready to use the chequebook this summer, as he believes that it will take as many as five players for the Light Blues to challenge Celtic, according to The Scottish Sun.
The Gers boast an eight-point lead at the top of the second tier, so appear to be well on their way to securing their return to the Scottish Premiership. And six-time league winner Goram believes that it is time for King to make a significant investment in the squad so that they are able to close the gap to the Hoops.
"Dave King has said there is that much money there to spend on players," he told The Scottish Sun.
"So if we can get four or five really good quality players there is no reason why we can't challenge Celtic.
"The manager has spent wisely. He didn't need £20m to get promoted. There should be a big chunk left."
While some may be concerned that all but three of Mark Warburton's signings have either arrived on a free transfer or on loan (via The Scottish Sun), their success in the league would suggest that they do not need to throw significant amounts of money at the squad this term, unless it is going to benefit them when they return to the top flight.
If Rangers play like they have done for the majority of the campaign, they should have little problem going up as champions. And if that proves to be the case, they may be grateful for the fact that they decided to take a slightly more cautious approach in the transfer market this season, as it may give them more financial muscle to cement the kind of challenge that Goram believes they are capable of.
