Sheffield United thumped League Two Gillingham in the previous round of the FA Cup as William Osula and James McAtee both scored twice.

Here are the highlights from that match.

Both Everton and Luton had to come through third round replays to set up today's meeting on Merseyside.

Andre Gomes' free-kick was enough to see Everton edge past fellow Premier League side Crystal Palace following a goalless draw at Selhurst Park.

Luton, Meanwhile, were pushed by League One side Bolton Wanderers.

But Rob Edwards' side fought back from a goal down to earn a 2-1 win away from home after being held to a goalless draw at Kenilworth Road.

There's another all-Premier League tie taking place at Goodison Park this afternoon, where Everton welcome Luton Town.

Just one point and one place separate the sides in the Premier League, with Everton just above the Hatters outside the relegation places following their 10-point deduction.

Luton have already enjoyed a victory at Goodison this season, winning 2-1 when the sides met in late September.

But Everton have never failed to progress in three previous FA Cup ties against Luton, albeit the most recent meeting came in the 1985-86 season.

On that occasion, Gary Lineker's goal gave the Toffees a 1-0 win in a sixth-round replay.

Scorer of Maidstone's first goal, Lamar Reynolds, speaking to BBC One: "Not a lot of people can say they get to this round, especially as a non-league club playing a team from the Championship. It’s amazing.

"It was massive. We knew counter attacks were going to be important. I was lucky enough to get a good finish.

"Sam (Corne) has run hard (for the second goal) and I’ve seen him, played it and it’s the cherry on the top."

A big talking point here is about tired legs and Leeds desperately wanting to avoid a replay. Daniel Farke’s side played last Sunday, then Wednesday and now today. It’s been gruelling even by Championship standards.

Plymouth supporters on the other hand are hoping the year ending in 4 brings them luck. They made the FA Cup semi-finals back in 1984. But it’s been 17 years since they last reached the 5th round.

Maidstone goalscorer Sam Corne, speaking to BBC One: "I don’t think I’ve got the words to describe it.

"We had belief and it showed on the pitch, that desire to put our bodies on the line.

"The manager said we had to have that belief not to sit too deep, to counter attack and if we did concede we may be able to nick another one and we did that.

"The fans aren’t going anywhere, they'll stay and celebrate. To follow us all the way to Ipswich, they are the 12th man for us and helped us through, especially in the later stages."

Maidstone goalkeeper Lucas speaking on BBC One: "It means a lot. I just want to thank my whole family, wife and everybody supporting us. My career in the last few years was not very good and now all the bad part comes in my head and we produce this. It's unreal.

"It's a normal day at the office! I had a great game. I am so happy I could help my teammates. We are in the hat again and hopefully I can get a move now to the Championship.

"What we have achieved is something unbelievable. To be in the last 16 teams in England it's brilliant. We kept fighting until the end, bodies on the line and everything."
