The excitement has faded away at Arsenal.
They are only eighth in terms of goals from open play, they have to improve.
At times they don't have the pace to come up the pitch and Kai Havertz can be isolated.
The fans want to see excitement now.

The Tamworth manager and the coaching staff are just urging the team to settle the game down and take the pressure off. This is where they are missing someone like Tom Tonks.

Brennan Johnson fires a low cross across the face of goal. No Spurs player is anywhere near.
It's like Spurs are just waiting for Tamworth to fold. No sign of that.
Tamworth 0-0 Spurs
Credit has to go to Tamworth for their fitness and concentration today. They are part-timers, and only train three times a week.
You would not think that, looking at the effort they have put in today.

The pressure is mounting now from Spurs and it's about concentration and communication for these Tamworth players as the mind and bodies begin to get tired.
Tamworth 0-0 Spurs
Spurs have started extra time as if they do not want penalties. They win a couple of early corners, but everything is repelled by Tamworth.
Hull 1-1 Doncaster
That's it. Penalties will be needed to separate Championship Hull and League Two Doncaster.

Tamworth players have put themselves in the shop window, all credit to them. Ange has learned a lot about some of the players today, most have let him down and themselves massively. It's not Ange's fault, no way has he allowed them to be complacent or prepared them properly. This is firmly on the players.

Tamworth 0-0 Spurs
Kai Williams is the latest Tamworth player to be booked. Four of their players have been carded today.
They have not been afraid of Spurs at all.

This is why replays need to be kept! Tamworth would be going to Tottenham Stadium, an absolute payday for a fifth tier part-time team. But, no! The powers that be don’t want that because players on £350K a week complain that they'd have to work 180 minutes a week for their dollar!

Brilliant shot, even better save.

Tamworth have done everything that was asked of them today and more. They have competed, they have been a danger and defensively they have been outstanding. They have been a threat. Spurs haven't been able to deal with them - they have been poor.

I'd say even if Spurs win this in extra time or on penalties this has been an embarrassing afternoon.
Alan
And this is what happens when you scrap replays. Tamworth have just gone and shown the FA what a laughing stock they are.

Hull 1-1 Doncaster
A rare late chance for Doncaster as debutant Hull keeper Carl Rushworth spills a cross, but he's bailed out by his defenders who clear.

Arsenal boss Mikel Arteta, speaking to BBC: "We thought about the best possible line-up, and we wanted to try and be better than Man Utd.
"We have a lot of games, and it is going to be an interesting week. Baring this in mind, we believe this is the best squad to start."
On Riccardo Califouri not being in the squad: "He had a light problem yesterday in training and he couldn't make the game."
On the loss against Newcastle: "Every three days we have a game and another opportunity to show the good things that we showed in that game.
"The players are trying their best, and we are supporting them."
On beating Man Utd earlier this season: "It is never two games that are equally the same - we are in a different moment."

He saw his name in the headlines! All he [Taom McGlinchey] had to do was square it, he had two players alongside him that had a tap in.
