Chelsea manager Jose Mourinho admits this season's FA Cup has been tarnished by the Wembley fiasco.
Mourinho was excited at the prospect of leading his team into the new arena for the end-of-season showpiece.
But, after several setbacks, the new 90,000-seater stadium in north London will not be ready until next year.
Chelsea will go back to Cardiff's Millennium Stadium if they beat Liverpool in Saturday's semi-final.
Mourinho said: 'We had the FA Cup in our minds since the beginning of the season because of the prestige of the competition and because we couldn't win it last season.
'But also because it should have been the first game at Wembley and that would have given it special meaning.
'I was very disappointed when I knew the final wouldn't be there.
'I was at the old Wembley as an assistant coach and I enjoyed it very much.
'I can imagine what the new one will be like and it would be a special feeling to go there as the Chelsea manager.
'We were waiting for the FA Cup final - although we don't know if we would be in it - and after that the Community Shield because we knew we would be going to that.
'But again it is not possible.'
Chelsea will be happy to return to the Millennium Stadium, however, if it means the chance of their first ever league and FA Cup double.
They are one point from clinching the title but must overcome Liverpool to reach the FA Cup final.
Mourinho said: 'Cardiff is a beautiful stadium and we have good memories. We won the Carling Cup and Community Shield in Cardiff and we would be very happy to go back.'
