Two goals for Harry Kane and one from Jan Vertonghen mean it is Tottenham who are safely into the fourth round of the FA Cup.

It was a fantastic finish!

It was a very dangerous cross and it landed just inside the 'D', Lichaj ran from right back, he brought it down with his first touch and volleyed it in with his second.

The keeper just watched it go in.

Just fantastic and a great celebration.

It's been a very good afternoon for Nottingham Forest.

Arsenal are dominating possession but Forest are creating chances and Ospina has had to work the harder of the two keeprs in this first half.

Brereton is getting in behind Mertesacker whenever he can.

Arsenal have relied on David Ospina today, but the goalkeeper is now struggling with a hand injury, sustained while making that latest save to deny Ben Brereton.

Matt Macey is the Gunners keeper if they need him, but at the moment Ospina is OK to carry on.

David Ospina is having a great game in the Arsenal goal and he again denies the lively Ben Brereton.

Forest have certainly had some chances to retake the lead. Will those misses come back to haunt them?

It was unlucky for Son. It was really good play by Alli, Trippier and Son out on the right. Trippier played a lovely ball through. Son tried to dink it but it's come back out.

Nearly 4-0. Son Heung-min's shot takes a deflection and that takes it on to the post.

George Francomb started his career at Tottenham, but was released at the age of 14. How he would love a goal against his former side. He has a chance, but his effort from 18 yards is easily dealt with by Michel Vorm.

Loser92: never a free kick. Arsenal gifted by the referee again.

Shaun Thacker: Can the FA also review diving in cup games? Disgraceful dive by Nelson to win the free kick for the equaliser there

Dave, Manchester: Pep may have been right about "The Harry Kane team", Spurs are completely reliant on him

Tottenham press for more goals. Dele Alli and Son Heung-min link up well and Son strikes at goal, but it is blocked by the lunging Abdul-Yussuf Oshilaja.

When you have to duck because you can’t see the other side of the pitch.

Here is the deflected strike from Tottenham's Jan Vertonghen which gave them a 3-0 lead.

He's gone off the pitch now but you can understand why his manager didn't rest him.

Watch below how Harry Kane added two more goals to his Spurs tally this afternoon.

Sloppiness at the back from the Arsenal defence and that allows Ben Brereton a chance and he weaves his way into the penalty area, but is denied by a fine save by David Ospina.

A good game, this one though as Arsenal then look to attack. End-to-end at the City Ground.

There will be no hat-trick for Harry Kane today as he is taken off. Georges-Kevin Nkoudou gets 10 minutes to impress.

Eric Lichaj puts Forest one up with a close-range header against Arsenal. The lead does not last long however.

Almost a hat-trick for Harry Kane, he strikes powerful from the edge of the penalty area, but is denied by a fine one-handed save by George Long.

With the flurry of goals, we failed to mention that Dele Alli has come on for Tottenham. He didn't get a good reaction from the AFC Wimbledon fans, because of his connection with MK Dons.

A rare non-headed goal for Per Mertesacker.
