The Gunners needed extra-time, but goals from Smith Rowe and Aubameyang secure a place in the fourth round. Thanks for joining us on the Gooner Fanzine live blog and we'll see you again on Thursday. Enjoy the rest of your evening.

Full-time! Arsenal 2-0 Newcastle.

117'- GOOOOAAAALLL ARSENAL! The Gunners secure their place in the next round as Tierney finally gets the assist he deserves, putting the ball on a plate for Aubameyang to turn home from close range. 2-0

109'- GOOOOAAAALLL! Arsenal look to have won it! Lacazette nods down a ball into the path of Smith Rowe and from a tight angle he tucks the ball into the far corner. Can the Gunners hold on?

106'- Back underway. Lacazette has replaced Pepe. 0-0

Half-time of extra-time. Arsenal 0-0 Newcastle.

101'- Arsenal nearly find the breakthrough as Saka is slipped in, but Newcastle just about clear his low cross into the six-yard box. 0-0

96'- Elneny's volley from the edge of the box comes down with snow on it. 0-0

94'- SAVE! Dubravka makes a wonderful diving save to deny Xhaka whose thunderous volley was bound for the back of the net. 0-0

93'- CHANCE! Tierney and Smith Rowe combine nicely down the left, with the latter seeing his effort blocked inside the area. 0-0

91'- Extra-time underway at the Emirates. 0-0

I've just seen that Leno save again and wow! It's a wonderful bit of goalkeeping from the German.

Full-time. Arsenal 0-0 Newcastle. The snooze-fest continues at the Emirates as we head to extra-time.

93'- Two very nervy moments for Arsenal as Leno makes an important save and then Smith Rowe is shown a red card for a challenge on Longstaff, but VAR changes the decision and the youngster stays on. 0-0

88'- Sorry for the lack of updates, but literally nothing is happening. Extra-time looms. 0-0

72'- Pepe drifts inside from the right and curls a left-footed effort towards the far post, but it zips wide of the upright. 0-0

66'- Double change for Arsenal as Saka and Xhaka replace Willian and Willock. 0-0

64'- CHANCE! Arsenal come close to the opener as Pepe clips in a cross and Willock meets it. He heads the ball down but Dubravka gets across to save. 0-0

60'- CHANCE! Elneny clips a ball through for Aubameyang and he takes the shot on, but his clipped effort from a tight angle drifts harmlessly wide of the far post. 0-0

56'- First Arsenal change as Smith Rowe replaces the disappointing Nelson. 0-0

56'- HUGE CHANCE! Newcastle should be ahead. Arsenal fail to clear a free-kick into the area and Hendrick drives the ball back in towards Carroll who turns it wide from six yards. 0-0

53'- Smith Rowe getting ready to come on for Arsenal. 0-0

46'- Back underway at the Emirates. 0-0

Half-time. Arsenal 0-0 Newcastle. Chances few and far between at the Emirates with both teams lacking some much-needed spark. Mikel Arteta will certainly be demanding more from his side at the break.

33'- CHANCE! Neat play between Aubameyang and Pepe allows the latter to break into the box, but he gets caught in two minds as to whether to cross or shoot and Dummett gets across to clear. 0-0

28'- CHANCE! Tierney does brilliantly down the left to drive beyond his man and then the cutback is on a plate for Nelson, but he takes a touch instead of shooting and Newcastle crowd him out. 0-0

25'- CHANCE! Arsenal close to opening the scoring as Aubameyang beats the offside trap and then forces a save from Dubravka before Willian skies the rebound over. 0-0

20'- Nervy moment for Arsenal as Nelson's sloppy pass allows Newcastle to counter, but Luiz does well to block Carroll's shot and then Almiron is offside. 0-0

18'- Nothing really going on at the moment. The tempo of the game is relatively slow with neither side creating anything of note. 0-0

9'- Arsenal try to break with Nelson and Lascelles comes across before chopping him down. The Newcastle skipper goes into the book. 0-0

3'- Another shot for Arsenal this time from Pepe as he makes Dubravka work. Good early intent from the Gunners. 0-0

1'- Arsenal have the first shot on target as Nelson forces Dubravka into a save down low. 0-0

1'- Underway at the Emirates. 0-0

Teams are out at the Emirates. Kick-off is moments away.

From footage on Twitter it looks like Martinelli rolled his ankle quite badly. Let's hope it's nothing too serious. Nelson now officially replaces him the starting XI.

Looks like it could be bad news for Arsenal and Gabriel Martinelli. The Brazilian has gone down injured in the warm-up with what looks to be an ankle problem. He's now gone down the tunnel in tears and Reiss Nelson looks likely to take his place in the starting XI, but we are still awaiting confirmation.

Arsenal and Newcastle have met 10 times before in the FA Cup. The sides have won four games apiece, with the Gunners winning the 1998 final 2-0 at the old Wembley and the most recent tie in 2008 thanks to an Emmanuel Adebayor brace and a Nicky Butt own goal.

Mikel Arteta makes seven changes from the win over West Brom, but he still names a strong team. David Luiz and Cedric come into the defence, while Willock, Elneny, Willian, Pepe and Martinelli also come into the side, with Aubameyang leading the line. What do you make of the starting XI?

Newcastle subs: Gillespie, M Longstaff, Ritchie, Gayle, Yedlin, Murphy, Anderson.

Newcastle team to face Arsenal: Dubravka, Krafth, Lascelles, Clark, Dummett, Hayden, Longstaff, Hendrick, Almiron, Joelinton, Carroll.

Arsenal subs: Runarsson, Chambers, Maitland-Niles, Xhaka, Saka, Nelson, Lacazette, Nketiah, Smith Rowe.

Arsenal team to face Newcastle: Leno, Cedric, Luiz, Mari, Tierney, Willock, Elneny, Pepe, Willian, Martinelli, Aubameyang.

Good evening and welcome to the Gooner Fanzine live blog as Arsenal begin their defence of the FA Cup at home to Newcastle United in the third round. Stay with us for all the latest from the Emirates.
