Where can you watch the FA Cup fifth-round ties?

The FA Cup is down to the last 16 teams, with eight ties across four days which will see the video assistant referee (VAR) - as well as new offside technology - introduced at this stage.

The fifth round starts on Friday when Aston Villa - without a major trophy since 1996 - host Championship strugglers Cardiff City (20:00 GMT) for a place in the quarter-finals.

There are four ties on Saturday, including Championship club Plymouth Argyle - who upset Liverpool in the fourth round - at Manchester City (17:45).

Holders Manchester United are at home to Fulham on Sunday (16:30) in one of three games being shown live on BBC platforms.

The eighth and final tie of the round sees Nottingham Forest play Ipswich Town at the City Ground on Monday (19:30).

All the games will be decided on the day.

If scores are level after 90 minutes then extra time will be played, with a penalty shootout to follow if the teams still cannot be separated.

BBC Sport will have coverage of all eight ties.

The final takes place at Wembley on Saturday, 17 May.

VAR & new offside technology

With no VAR in operation, there were several controversial moments in the last round - not least when Manchester United's Harry Maguire headed an injury-time winner to seal a 2-1 win against Leicester City.

Maguire appeared to be offside when Bruno Fernandes sent a free-kick towards the back post but the goal stood - and Leicester went out.

Even United boss Ruben Amorim admitted his team's winning goal should not have stood.

However, VAR will be introduced - as planned - from the fifth round onwards.

It will be active across all eight ties including at Deepdale, where Preston host Championship rivals Burnley on Saturday.

This will include in-stadium VAR announcements, where match officials will announce their final decision in relation to reviewed incidents to provide "improved clarity and understanding" for fans and viewers.

Semi-automated offside technology will also be used in all seven matches taking place at Premier League grounds.

It is the first time it will be used live in competitive matches in English football.

The system aims to remove some elements of human subjectivity by replacing decisions made by officials with automated ones taken by technology.

If successful, the Premier League will look to implement the technology before the end of this season.
