Tosin Adarabioyo has reached an agreement to join Chelsea and is scheduled to undergo a medical next week.
The Fulham central defender has been at the centre of a tug-of-war between Newcastle, who are understood to have made a generous formal offer to Adarabioyo a fortnight ago, and the Blues and has been deliberating his future since the end of the season.
But the 26-year-old is now set to become Enzo Maresca's first signing at Stamford Bridge after agreeing to move across west London.
Mail Sport understands the centre half will sign a long-term contract upon completing a medical when he returns from holiday next week.
