MATCH PREVIEW
Second-placed Cardiff City have taken seven points from their last three matches and have been a bogey side for Bristol City in recent years.
They are unbeaten in seven matches against the Robins, and did the double over them last season, scoring nine goals and conceding none.
Millen relishing 'massive' challenge
Unbeaten at home since February, the Welsh club will be looking to extend that run and inflict more misery on a side that are bottom of the table and without a win in five matches.
The West Country outfit are enduring their worst start to a league season in 28 years. Not since 1982, when they were in the bottom division, have they had only six points after their first 10 games.
