Chelsea have signed nine players this summer for about £140m.
Midfielders Kiernan Dewsbury-Hall, Renato Veiga and Omari Kellyman, goalkeeper Filip Jorgensen, defenders Tosin Adarabioyo, Aaron Anselmino and Caleb Wiley, winger Estevao Willian and striker Marc Guiu have all joined.
The Blues look set to sign their eighth senior goalkeeper, Mike Penders, for £17m – although he is likely to be loaned back to Genk – and hope to bring in Atletico Madrid forward Samu Omorodion for £34.5m.
If Penders, Omorodion and Neto all join, the 12 summer signings would take Chelsea’s spending to more than £240m.
About £90m has been recouped through the sales of Ian Maatsen, Lewis Hall and Omari Hutchinson while Conor Gallagher is expected to join Atletico Madrid for £33m.
Penders, Omorodion and Neto’s arrivals would take Chelsea’s senior squad – as it is listed on the club’s website – to as many as 50 players.
Clubs must submit a Premier League squad list with a maximum of 25 players after the closure of each transfer window but can use as many players under the age of 21 as they wish.
