FCSB boss Elias Charalambous stressed under-pressure Philippe Clement's problems are of no interest to him.
But he insists there's no chance they will underestimate Rangers for this week's Europa League showdown.
Rangers were heavily criticised after blowing their chance to close the gap at the top of the Premiership to Celtic and Aberdeen after a timid 1-0 defeat at Kilmarnock.
FCSB got the perfect boost for their trip to Scotland with a 2-0 derby win away at bitter rivals Dinamo Bucharest on Sunday.
And the manager of the Romanian former European Cup winners was quizzed on Rangers' troubles after the victory.
He said: " I know nothing about the problems of the Rangers manager. We don't know what is going on with them.

"But we do know it will be a tough test in Europe.
"We know the quality of Rangers. They are a big club and it will be much different in Glasgow where they have home advantage.
"To win this game, we will have to play top quality football.
"Psychologically, this derby victory is important. European games are different though, especially with Rangers.
"At the moment, we have games every three days and that is actually helping us.
"When we go to Glasgow, we are going all out for victory. That's my only focus.
"But I am happy with the way the team are playing. I think the attitude and focus was good. The tactical instructions were followed and even when we were 1-0 up, we continued to press for another goal."
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
