Celtic manager Brendan Rodgers has told Ibrox chairman Dave King that he has no interest in "what goes on over the garden fence".

King was quoted as saying that Celtic would “collapse like a pack of cards” should the Ibrox side put a spoke in the wheel of their ambitions to return an historic ten-in-a-row, a prospect that looks increasingly plausible.

Celtic have qualified for the last two successive seasons for the group stages of Europe’s premier tournament, and revenue figures released in February this year revealed the significant boost to income that participation generated with the club showing a sum of £30.9m net cash in the bank.

“Before I came here the club hadn’t been in the Champions League for two years and that’s a way of generating finances which can’t be matched in any other way,” said Rodgers.

“But what we have here is a very good board of directors and a major shareholder who have a very clear strategy and vision for the club and I’ve been able to come in and add a football vision to that – and, ultimately, it’s about what happens on the field.

“Celtic are not going to win the league every year, but there is a great base here. There’s no guarantees that Celtic will get through four rounds of qualification.

“But there is a strategy here - one for the Champions League and one for the Europa League.

“The money that is generated from the last few years puts the club on a wonderful footing and allows us to grow on and of the pitch and that’s my only concern.

“I’ve always said we are not defined by Rangers or anyone else and that continues.

“I don’t know Mr King. I’ve never met him and would never portray to know what goes on at Rangers,” said Rodgers. “I don’t worry about what goes on over the garden fence.

“You look after your own house, get that the best you can. Of course you know the different markets and what competitors are doing, but we are defined and measured by ourselves, not by anyone else. That’s the most sensible way to look at things.

“We get the football strategy right knowing there is a commercial knock on. If you get success on the field and have an identity and a plan and improve on it then it’s great. If I look at Man City and their funds and think ‘bloody hell, we’ve no chance’ then that’s not the way it works.

"But we are a stable club with a lot of intellectual capital in the club and the interests are aligned. That gives us a stable base and it all works very simply.”
