Dafydd Pritchard
BBC Sport Wales at the Swansea.com Stadium
Nobody's missed this. The eeriness of an empty stadium.
Swansea have made the brighter start in this tie, which has the feel of a training session as you can hear every order being barked from the coaches on the touchline.

Great work from skipper for today Mateo Kovacic, who surges through the middle, feeds Hakim Ziyech, whose square ball is turned in from close range by Timo Werner.

FT: Newcastle 0-1 Cambridge
Fara Williams
Former Liverpool and England midfielder on Final Score
It has to be the upset of the round. Going to a packed St James' Park and put on the performance they did.
Credit to the Cambridge keeper Dimitar Mitov with nine saves. And not just any saves, they were match-winning saves. He had a great performance, Cambridge had fantastic performance.
There are still in major trouble at Newcastle.

Tyler Smith's goal puts Hull City in the lead
What a start for Hull City!
An absolute disaster for Everton. The Premier League side are caught out from a free-kick, as Tyler Smith heads in unopposed from close-range.
A first-minute set-back for Rafael Benitez's side.
The FA Cup has delivered and then some so far today, will the late kick offs come up with the goods as well?
We're getting under way in the five late games.
West Brom 1-2 Brighton
It's been pretty dead in extra-time. Brighton win a corner which comes to nothing. West Brom can't do anything. We need the whistle to go really!
