How to follow FA Cup fourth round on BBC
The FA Cup fourth round gets under way on Friday when holders Manchester United host Leicester City (20:00 GMT) - the first of 16 ties over five days.
Leicester are managed by Ruud van Nistelrooy, who scored two goals in United's 3-0 win over Millwall in the 2004 final.
Van Nistelrooy was interim United boss when they beat Leicester 3-0 at Old Trafford in the Premier League on 10 November before Ruben Amorim took charge on a permanent basis.
Record 14-time winners Arsenal were knocked out in the third round by United, with West Ham and Brentford the other Premier League clubs to fall in the last round.
At least four more top-flight clubs will go out over the next few days.
Following the decision to scrap replays from the first round onwards, all games will be decided on the day.
If scores are level after 90 minutes 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 16 ties.
