....but we think they'll need some tighter closing down against Robbie's All Stars.
Here's some more action from earlier.
Composure.

But don't forget you can also keep on watching Shay Given, who is also taking on a 12-hour challenge, facing penalties to raise more money for Sport Relief.
Here's one famous face who was determined to win a battle of opposing Manchester loyalties...
During the break we're being entertained by the University of Manchester cheerleading team.
"Two thunder strikes from Jade - worthy winners of the game," says Brown.
And it's Jade who makes the difference in the closing stages as it finishes 9-8 to Port Talbot.
Still 47-42 to the Allstars overall though.

"Jade's just smashed it home with her left foot - amazing finish. The game's tight now," he says.
It's 7-7.
And James makes him pay, scoring again to put Port Talbot 5-4 up.

"Oh Savage, should've got on the end of that one."
You can see what it means to James as he puts one past Rachel Yankey, who has swapped places with Savage.
The young man gets a high-five off Michael Vaughan for his efforts.
Savage's performance is affecting the goalkeeper at the other end as he sees three go through his legs in quick succession as the Allstars recover to make it 4-2.

And it's soon 2-0 to Port Talbot.
"Savage in goal is turning out to be a disaster for the Allstars."
Robbie Savage has gone into goal and is at fault for the first goal.
A poor clearance allows Jade to strike it past Savage, who barely moves.
It's Port Talbot Town Soccability team next as the opponents for the Allstars.
Here's the difference that Peter Reid has made to the Allstars team (see 14:05)...
