Chelsea will step up their attempts to sign the Brighton midfielder Moisés Caicedo and the Villarreal striker Nicolas Jackson this week.
Jackson, a 21-year-old striker, has agreed personal terms and Chelsea are considering whether to trigger his £30m release clause. The Senegal international failed a medical at Bournemouth in January and has been tracked by Aston Villa and Everton, but Chelsea’s interest has intensified following recent discussions with the player’s camp.
