The fixture averages 5.0 cards over the last nine meetings with only one fixture producing less than three cards. The referee is Oliver Langford, who dished out six cards in this only appointment so far this season.

There were 5 cards in Swansea’s season opener against Middlesbrough and 4 in their previous match against Preston.

The Swans will play with width with Ronald and Ji Sung Eom. They have won five and nine corners so far this term with an average of 5.70 from their home fixtures last season.

In their last 10 home fixtures they have won at least five corners in eight. Cardiff have conceded at least five corners in 18 of their 23 away fixtures last term.

Over the last 12 head-to-heads this game has averaged just 2.17 goals with only four seeing three or more goals.

In only two fixtures between these sides going back to 2013 has there been four or more goals. Swans home games last term averaged 2.35 goals

The Swans conceded an average of 4.61 corners at home last term, allowing their visitors to win three or more in 18 of 23 fixtures. Cardiff have won four and then five corners from their opening fixtures.

Last term they averaged 4.18 corners and won three or more in 18 away fixtures, they’re always a threat from set pieces and that could be their best chance of unlocking the home defence.

Perry Ng will be facing Ronald, who was fouled five times in his only league start this season.

Against Preston, the Swansea man was up against full back Brad Potts, who committed four fouls against the attacker. If Ng commits that many fouls against Ronald this weekend, then he will do well to avoid a card.

Ng himself was highly involved in the action in Cardiff’s defeat to Burnley, being involved in 11 duels – that is likely to be the case here too in the Welsh derby. Ng is one of the leaders in this Cardiff set up and will try and set the tone.

Siopis will sit deep and be asked to look after Ollie Cooper, who so far has been fouled more times per 90 mins than any other Championship player.

The Swans’ clever midfield and forward players will look to cause problems, which will demand close attention from the Bluebirds.

Siopis was involved in 9 duels against Burnley last time out and won 8 of them, he’ll likely be at the heart of a similar amount here and if his success record isn’t as high, the Cardiff man could see a card.
