Romelu Lukaku (25)
Jordan Pickford (Sunderland, £30m), Michael Keane (Burnley, £25m), Davy Klaassen (Ajax, £23.6m), Sandro Ramirez (Malaga, £5m), Wayne Rooney (Manchester United, free)
Romelu Lukaku (Manchester United, £75m), Gerard Deulofeu (Barcelona, £10.5m), Tom Cleverley (Watford, £8m)
Have done some good business and did it early, allowing their arrivals to integrate. Koeman has bolstered his spine, with Pickford, Keane and Klaassen all solid additions.
Replacing Lukaku’s 25 goals will be tough. For all the romance of Rooney’s return, he is nowhere near the player he was.
Jordan Pickford. Can theoretically become England’s No1 for the World Cup.
Capable of a push for a top six finish, and they are the team best equipped to pounce should one of the big boys stumble.
With Lukaku gone, they are lacking an X-factor star, with too many 7/10 players only fleetingly capable of the fantastic. Europa League beckons.
Frank De Boer
Christian Benteke (15)
Jairo Riedewald (Ajax, £8m), Ruben Loftus-Cheek (Chelsea, loan)
Steve Mandanda (Marseille, £2.5m), Fraizer Campbell (Hull, free), Mathieu Flamini (free agent), Joe Ledley (free agent), Zeki Fryers (Barnsley, free)
An attack-minded Frank De Boer will take his Ajax template and unlock the attacking potential of Zaha, Jason Puncheon and Christian Benteke up front.
Liverpool loanee Mamadou Sakho played a huge role in saving Palace last year and without him the defence looks frail.
Loftus-Cheek. Limited to only six appearances from Chelsea’s bench last season, a loan move to Palace offers the technical but rangey midfielder a chance to prove his worth in the Premier League.
A mid-table finish in De Boer’s first season without the threat of relegation, building on the Sam Allardyce era.
May not struggle as much as last year but will be looking over their shoulders in the lower half of the table.
Diego Costa (20)
Alvaro Morata (Real Madrid, £70.6m), Tiemoue Bakayoko (Monaco, £40m), Antonio Rudiger (Roma, £31m), Willy Caballero (Manchester City, free)
Nemanja Matic (Manchester United, £40m), Nathan Ake (Bournemouth £20m), Juan Cuadrado (Juventus, £17m), Asmir Begovic (Bournemouth, £10m), Bertrand Traore (Lyon £8.8m)
Last season’s runaway champions have added real quality in Morata and Bakayoko, plus Conte was a repeat title winner at Juventus.
Question marks exist about whether their squad is deep enough to handle the return of Champions League football.
Morata will be determined to prove he can start every week for an elite club. With World Cup 2018 on the horizon, he’ll be desperate to impress.
Chelsea will pick up where they left off last term, with the sidelining of the fractious Diego Costa strengthening the unit.
More points will be dropped as the demands of European football takes hold. Hazard will again need to be at his inspirational best to fuel a competitive title defence.
