Cardiff City owner Vincent Tan has warned fans he could sell up over their protests.
The Malaysian â€” who bankrolled the Bluebirdsâ€™ promotion charge â€” sparked controversy last summer when he changed the clubâ€™s home kit from blue to red.
Tan said: â€œI am surprised there are fans against the colour. Iâ€™m actually quite disappointed with that.
â€œI 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.
â€œWe spent Â£15million last season to buy players and we went up. Thatâ€™s how we got up.
â€œIâ€™m disappointed that after 51 years of not being in the top flight that there are still some fans who donâ€™t think we have done a good job.
â€œI may say maybe they are not grateful, so that part is disappointing. But like anything in life in democracy you wonâ€™t have 100 per cent support.
â€œWe have to think that those against us are about five per cent. We will try to live with that but it is disappointing.
â€œIf too many of them show we are not welcome, maybe you will have a new owner."
