"This is great news for TNS, the Welsh Premier League and Welsh football as a whole," said Harris.
"Our players and management are really excited at the prospect of playing at the greatest soccer stadium in the UK against one of England's finest teams, managed by a footballing legend like Kevin Keegan.
"As soon as we heard the draw, we knew we had to do something special with our home fixture to do justice to the occasion.
"There could be no better setting that the Millennium Stadium."
"We know it's a few hours drive, but we'd like to think that fans would see it as a special occasion. How many times are we going to be playing at the Millennium Stadium?"
