It's almost 20 years since the FA announced all FA Cup semi-finals would be at Wembley to pay off the building costs, yet some people still go on about neutral venues. It will never happen so instead we need to apply pressure on the FA to have all semi-final options decided before the quarter-finals are played, and confirm them as soon as the semis are drawn. - And these should be sensible options not ones that would immediately cause transport anxiety such as half five on Sunday. If the Sunday semi-final has to be played at the same time as a PL game then so be it.
The only exception would be if a Thursday League team was drawn against a team playing in the CL the following Tuesday, which would result in a problem anyway.
