Chelsea are expected to be one of the major players on deadline day, having completed a deal for Wesley Fofana on Wednesday.
The Blues have been one of the big spenders during the transfer window and owner Todd Boehly is eager to bolster his squad after a slow start to the season.
Barcelona forward Pierre-Emerick Aubameyang has been linked with the Blues, along with Anthony Gordon, although Everton boss Frank Lampard insists he is not for sale.
TOP STORY – CHELSEA OFFERED CHANCE TO SIGN PSG'S NEYMAR
The Daily Mail claims Chelsea have been offered the chance to sign Neymar, but the Times reports that Paris Saint-Germain are now refusing to sell him in an apparent U-turn.
The 30-year-old Brazil international had been linked with a move away from Paris during the off-season, although nothing substantial materialised.
Chelsea were approached about Neymar, with PSG potentially open to letting him go as they seek to avoid any issues with UEFA's Financial Fair Play guidelines.
