Chelsea boss Carlo Ancelotti wants to splash out on Bolton Wanderers defender Gary Cahill.
The People says the Italian will make Bolton centre-half Cahill his only major signing of the transfer window.
The Blues have curbed their lavish spending over the past year to give young players a chance.
But a worrying lack of strength in depth has seen Chelsea fall way off the pace in the Premier League.
Chelsea will offer £15 million for Cahill this week, though Trotters boss Owen Coyle warned yesterday he would not consider selling for anything less than £20 million.
