Cardiff City owner Vincent Tan has warned fans he could sell up over their protests.
The Malaysian - who bankrolled the Bluebirds' promotion charge - sparked controversy last summer when he changed the club's home kit from blue to red.
Tan said: "I am surprised there are fans against the colour. I'm actually quite disappointed with that.
"I was willing to invest and put in a lot of money into the club that several times could have gone bust and had financial trouble and a big court case with the former owner.
"We spent £15million last season to buy players and we went up. That's how we got up.
"I'm disappointed that after 51 years of not being in the top flight that there are still some fans who don't think we have done a good job.
"I may say maybe they are not grateful, so that part is disappointing. But like anything in life in democracy you won't have 100 per cent support.
"We have to think that those against us are about five per cent. We will try to live with that but it is disappointing.
"If too many of them show we are not welcome, maybe you will have a new owner."
