On the pitch, Cardiff will be looking to dent Manchester City's title hopes later, while boosting their own chances of avoiding relegation.
That would be a big upset, the biggest of the season according to the bookmakers.
Cardiff manager Neil Warnock said: "We've got to do our best in the game. I doubt any of our squad could get in either two of their first teams.
"They've taken the Premier League to another level. And you're not only putting your wits against the very best - possibly in Europe - but it's the highest odds in a game this season; 40/1 in a two-horse race. The bookies say they've never seen betting like it."
