STUART GIBSON admits Rangers must 'figure out a way' to boost the funds boss Michael Beale will be given to rebuild the Ibrox squad this summer.

Beale made his first moves in the transfer market during the January transfer window as Todd Cantwell and Nicolas Raskin signed long-term deals in Glasgow.

The 42-year-old caused a stir when he stated that Celtic counterpart Ange Postecoglou was a 'lucky man' given the budget that he has had to spend to make his mark at Parkhead.

Rangers are now 'financially sustainable' in the eyes of Gibson, the third largest shareholder, following years of spending to accumulate to close the Old Firm gap.

But the Japan-based investor - who this week defended the roles of Ross Wilson and executives Stewart Robertson and James Bisgrove - knows more work must be done to regain top spot in Scotland and the Premiership title.

Speaking in part two of an interview with podcast This Is Ibrox, Gibson said: “In terms of where they’re at now, and where they’re supposed to be when I first had the initial conversation, I think they’ve achieved it.

"They’re sustainable now. But we’re second in the league. We’re nine points behind Celtic and that’s just not acceptable.

“That’s something we need to fix. As our new manager said recently and he got into a bit of trouble: ‘The Celtic manager has been lucky he had such vast sums at his disposal’.

"That’s good for them but they basically had no one to beat for ten years. They should have accrued that wealth anyway.

"We’d have accrued that same wealth had we been in that position but again we’re behind Celtic so we still have to have more money to be able to go into the transfer market, I think in a bigger way.

“I think we probably need a handful of players to be honest during the summer and they’ll probably cost more than £1m or £2m a time so we do need to figure out a way to actually increase that pool of money that is available for the Director of Football.”
