Swansea v Preston
Friday 22 December, 19:45

Bobby Madley has been a good referee for cards punters this season and that's an angle worth pursuing in south Wales on Friday night.

Madley averages 4.89 yellow cards per game in the Championship so far, with four reds shown in his nine matches. That's well above average.

Here, he takes charge of two teams in need of a result after recent poor runs.
Neither is in real trouble but Preston have stuttered after a good start, while Swansea's form recently cost boss Michael Duff his job - they've now won just one of their last eight and are a little too close to the drop zone for comfort.

Both sets of staff and fans will be demanding a committed performance in a bid to lift pre-Christmas spirits.

Leg 1: Preston 2 or more cards

Let's start by backing Preston for 2 or more cards.

They've landed this in 82% of their league games so far this season which is the same percentage as Swansea's opponents have delivered on this bet.

Overall, only two Championship sides have had more bookings.

Leg 2: Swansea 2 or more cards

The hosts get the nod for the same bet.

It's one they've landed in 14 of their 22 games so 4/51.80 about it occurring again looks decent, particularly given the referee appointment.

Caretaker-boss Alan Sheehan praised an "aggressive" performance with "high intensity" against Middlesbrough last week (when they picked up two cards) and so similar will be expected here.

Leg 3: Brad Potts to be shown a card

That double pays around even money but to make it into something tasty, it's worth adding Brad Potts to be shown a card.

The Preston midfielder has been carded in six of his 21 Championship appearances this season. That puts him well on course to better last season's still-decent tally of seven.

The only game Potts hasn't started was when he was suspended, while last week was the first time he'd been taken off.

4/15.00 about Potts adding another card here looks a little on the large side and helps take our Bet Builder up close to 7/18.00.
