John Brown has told The Glasgow Evening Times that Rangers may need to sign as many as seven new players in the summer transfer window.
Rangers manager Mark Warburton recently told The Scottish Sun that he wants to make five new signings for next season.
Brown, who played for the Gers in the 1980s and 1990s and is a club legend, believes that the Glasgow giants may need to sign more if they get promoted to the Scottish Premiership.
“I think the manager has said that from next season he is looking for five new players and you could be adding more on in terms of back-up,” Brown told The Glasgow Evening Times.
"Players you can rely upon to come in and put pressure on the starting eleven. They have been roughly the same guys all season. There has not been too many forcing their hands.
“So I think five could be six or seven if they want to be a force next season - if Rangers get to the Premier League.”
Rangers are at the top of the Scottish Championship table at the moment with 59 points from 23 matches.
Mark Warburton’s side are eight points clear of second-placed Hibernian, who have a game in hand.
The Glasgow giants are favourites to gain automatic promotion to the Scottish Premiership at the end of the season.
It will take some time for Rangers to start challenging Celtic for the league title, but if they sign quality players in the summer, then they will give themselves a good chance of doing just that.
