Manager: Steve Kean.
2010-11 season: New owners Venky's sacked Sam Allardyce in December as he was not deemed conducive to their aspirations of Champions League football, and promptly saw the club sucked into a relegation battle under his replacement. Attempts to sign Ronaldinho and David Beckham also proved unrealistic and Venky's failed to shake off initial scepticism surrounding the new regime.
Strengths: Rovers have a nice blend of experience and promise. Players such as Michel Salgado, Paul Robinson and Ryan Nelsen are real leaders while David Hoilett is the club's brightest young talent and is in talks over a new contract at Ewood Park.
Weaknesses: The loss of Phil Jones to Manchester United deprived the club of one of England's outstanding young players and a versatile performer. Meanwhile, Venky's have struggled to bring in new faces this summer and the squad at Kean's disposal lacks quality and depth as a result.
Key man: Ryan Nelsen. With Jones leaving for United and Chris Samba being the subject of interest from Arsenal, Rovers will rely on the New Zealand international like never before this season. Nelsen is a consummate professional and a calming influence in defence, making him a valuable asset for a side that will find themselves under pressure at regular intervals this season.
Ins: David Goodwillie (Dundee United, £2m).
Outs: Phil Jones (Manchester United, £16.5 million); Frank Fielding (Derby, £400,000); Jordan Bowen (released); Jason Brown (released); Zurab Khizanishvili (released); Marceo Rigters (released); Michael Potts (released); Benjani Mwarurawi (released); Aaron Doran (Inverness CT, free).
Manager: Neil Warnock.
2010-11 season: Champions. QPR finished top of the Championship by four points although their promotion was briefly threatened by an investigation into the transfer of Alejandro Faurlin. QPR were found guilty of two breaches of third-party ownership rules but escaped without a points deduction.
Strengths: Retaining Adel Taarabt despite interest from big-spending Paris Saint-Germain was a real coup and QPR will expect their captain to build on the 19 goals he scored last season when being named Football League Player of the Year. Warnock has also added Premier League experience in Kieron Dyer and Danny Gabbidon, though both players have suffered fitness problems in recent seasons.
Weaknesses: Despite their owners having substantial financial resources at their disposal, Rangers have been afforded little money to play with in the summer transfer window and they are consequently suffering from a lack of strength in depth and top-flight quality. Though Jay Bothroyd has arrived from Cardiff City, they still look light in attack.
Key man: Taarabt. A complete no-brainer. The midfielder is by far and away QPR's most influential player and as well as scoring 19 goals last season Taarabt claimed 16 assists. His dribbling and his direct approach make him a nightmare for opposition defenders.
Ins: Jay Bothroyd (Unattached, free); Kieron Dyer (Unattached, free); Danny Gabbidon (Unattached, free); DJ Campbell (Blackpool, £1.25m).
Outs: Lee Brown (released); Pascal Chimbonda (released); Elliott Cox (released); Gavin Mahon (released); Joe Oastler (released); Josh Parker (released); Romone Rose (released); Georgias Tofas (released); Bagasan Graham (Cheltenham Town, free); Peter Ramage (Crystal Palace, loan).
Manager: Brendan Rodgers.
2010-11 season: Swansea became the first Welsh side to reach the Premier League courtesy of a 4-2 victory over Reading in the Championship play-off final on May 30. Rodgers' side won promotion in some style, earning them the nickname 'Swanselona' thanks to their slick, possession-based approach to the game.
Strengths: Rodgers has his side set up to dominate possession and they do so very well, with their short-passing style seeing them impose themselves on opponents. Meanwhile, in Scott Sinclair they boast a player who scored 22 goals last season.
Weaknesses: Swansea's summer signings have been solid rather than spectacular and there is a real concern that their adventurous approach will leave them open to punishment at the hands of the Premier League's bigger sides. They lack top-flight experience in all areas of the pitch.
Key man: Scott Sinclair. His last spell in the Premier League saw him score just one goal in 18 appearances for Wigan in the 2009-10 season but the former Chelsea forward has matured since. A threat either out wide or drifting into central areas, Sinclair demonstrated his worth when scoring a hat-trick in the play-off final.
Ins: Leroy Lita (Middlesbrough, £1.75m); Danny Graham (Watford, £3.5m); Jose Moreira (Benfica, undisclosed); Steven Caulker (Tottenham, loan); Wayne Routledge (Newcastle, undisclosed).
Outs: Gorka Pintado (released); Dorus de Vries (Wolves, free); Darren Pratley (Bolton, free); Scott Donnelly (Wycombe Wanderers, loan).
Manager: Paul Lambert.
2010-11 season: Losing just eight of their 46 League games, Norwich secured successive promotions when finishing second in the Championship. The Canaries finished only four points shy of champions QPR but scored a league-high 83 goals as they ended their six-year absence from the top flight. Their success came just 18 months after a 7-1 loss to Colchester United on the opening day of the League One season.
Strengths: Lambert's pedigree as a manager is hugely impressive and the Scot is the club's biggest asset; he has been coveted by rival clubs, and for good reason. Norwich also have an ambitious young squad.
Weaknesses: Norwich have a distinct lack of top-flight experience in their ranks and their summer additions have been on the modest side. Back-to-back promotions mean the Canaries are likely to be ill-suited to the demands of the Premier League.
Key man: Grant Holt. The striker scored 21 goals in Norwich's promotion campaign and also contributed 14 assists as he proved to be a crucial cog in Lambert's attack. The 30-year-old, who captains the side, has spent successive seasons in League Two, League One and the Championship and finally has his shot at the top flight.
Ins: James Vaughan (Everton, undisclosed); Steve Morison (Millwall, undisclosed); Elliott Bennett (Brighton, undisclosed); Ritchie De Laet (Manchester United, loan); Anthony Pilkington (Huddersfield, undisclosed); Bradley Johnson (Leeds, undisclosed); Kyle Naughton (Tottenham, loan).
Outs: Matt Gill (released); Jens Berthel Askou (released); Sam Habergham (released); Owain Tudur-Jones (Inverness CT, free).
