Watford will travel to Millwall in the fourth round of the FA Cup.

The Hornets were in the final throes of the draw as it was again decided they will face lower-league opposition, following Saturday's 2-0 victory over Burton Albion.

Watford were semi-finalists in the competition last season, before losing 2-1 to Crystal Palace at Wembley.

The game will be played over the weekend of January 27-30, depending on whether the tie is chosen for television.

Millwall are 10th in League One but are currently on a five-match unbeaten streak - and have already seen off one Premier League side in the competition this season, beating Bournemouth 3-0 at The Den last weekend.
