Neil Lennon does not believe Rangers or Aberdeen will spend big in their bid to catch up with Celtic but warned that the Parkhead club have the cash in reserve to see off any challengers.

Former Ibrox director Dave King, who lost £20m at the Govan club during a previous regime, is looking to effect change at Rangers with a fresh share issue, and was reported as saying he is prepared to put in another £30m in his bid to make the Scottish League One champions competitive with their traditional city rivals again.

The South Africa-based Glasgow businessman's claims came a couple of days after Aberdeen chairman Stewart Milne, celebrating the Dons' Scottish League Cup final victory parade in the Granite City, told fans that he would "do everything in our powers" to get closer to Celtic in the league.

However, ahead of the Scottish Premiership clash with Partick Thistle on Wednesday night, when Celtic could win the title if Aberdeen were to drop points against Ross County on Tuesday, the Hoops manager played down the prospect of rival clubs spending big money to force a challenge.

Lennon said: "I wouldn't imagine that would happen. I think the owners of clubs are far too astute for spending big money and trying to chase it.

"I think they will build brick by brick over maybe the course of two, three, four seasons and really try to close the gap.

"We haven't spent an amazing amount of money over the last couple of years so we still have some stock in the bank if we need it.

"But no, I can't imagine clubs like Aberdeen or Rangers at this stage, will start throwing millions of pounds at it to chase it."
