Hull City chairman Paul Duffen is cautious over plans to expand the KC stadium.

"We've got to remember that it was only March of this year that we played Southampton in front of 15,000 people when we were on the verge of promotion to the Premier League for the first ever time" said Duffen.

"One has to be very careful that you don't take on capital infrastructure plans on the back of what could be fickle support. I need to be convinced about that."
