Nottingham Forest will take on six new teams in the 2019-20 Championship season following promotion and relegation at the end of the previous campaign.
After Norwich City, Sheffield United and Aston Villa won promotion to the Premier League and Rotherham United, Bolton Wanderers and Ipswich Town dropped into League One, we take a look at the new opponents for Martin O’Neill’s side.
Stadium: Cardiff City Stadium
Manager: Neil Warnock
Last season: Premier League, 18th
Top scorer: Bobby Reid, Victor Camarasa (5)
It was an immediate return to the Championship for Neil Warnock's Cardiff side as they remained in the top flight for just one season following their second-place finish in the 2017-18 campaign.
The Bluebirds found life tough at the top but will have plenty of quality at their disposal to mount a serious challenge for promotion once again.
With the experienced Warnock at the helm, Cardiff are sure to be among the frontrunners.
Stadium: Craven Cottage
Manager: Scott Parker (caretaker)
Last season: Premier League, 19th
Top scorer: Aleksandar Mitrovic (11)
A season which promised much in the summer with some high-quality additions ultimately proved disappointing for Fulham as they immediately returned to the Championship.
Slavisa Jokanovic and Claudio Ranieri both struggled for results as manager before Scott Parker took the reins as it will be the former Cottagers midfielder who is likely to lead them in the upcoming season.
Stadium: John Smith’s Stadium
Manager: Jan Siewert
Last season: Premier League, 20th
Top scorer: Karlan Grant (4)
Huddersfield's two-year stay in the top flight came to an end last season as they suffered the joint-earliest relegation from the Premier League, along with Derby County's effort in 2008.
They picked up five more points than Derby that season though and Jan Siewert will be hoping that they can find the back of the net on a more regular basis in the Championship than the 22 they managed in the last campaign.
Stadium: Kenilworth Road
Manager: Graeme Jones
Last season: League One, 1st
Top scorer: James Collins (25)
Back-to-back promotions for Luton Town means they return to the Championship for the first time since 2006-07.
Their promotion from League Two and the first half of last season was orchestrated by Nathan Jones, who left to join Stoke City in January, but club legend Mick Harford stepped in to see them over the line with former Wigan, Swansea and Everton coach Graeme Jones appointed manager for the upcoming campaign.
Manager: Daniel Stendel
Last season: League One, 2nd
Top scorer: Kieffer Moore (17)
Barnsley continued their yo-yoing between League One and the Championship with promotion back to the second tier with a second-placed finish.
The Tykes made an immediate return with the goals of Kieffer Moore and Cauley Woodrow helping them fire straight back up.
Stadium: The Valley
Manager: Lee Bowyer
Last season: League One, 3rd (play-off winners)
Top scorer: Lyle Taylor (25)
Uncertainty off the pitch failed to distract Charlton on it as they secured play-off delight with victory over Sunderland at Wembley.
A three-year absence from the Championship came to an end with Patrick Baur's late winner under the arch and Lee Bowyer will be looking forward to leading his boyhood team back in the second tier.
