There's just something about the FA Cup that defeats even the great minds of football. It was Guardiola last season, now Ranieri and Puel, amongst many others. Who knows what it is, sorcery, who knows.
But that's why we love this competition
I think it's the FA Trophy where the teams before hand can agree if they want extra time or a replay if the match ends in a draw.
You can see why some teams would want a replay (small team against a Premier League team) but in this instance, extra time would have been beneficial for both sides.
As part of the new overseas FA Cup TV deal, every game from the 3rd Round onwards is broadcast, so there will be a stream. That's why there are only 10 games at 3pm.
