Chelsea boss Frank Lampard is weighing up whether to sacrifice one of his centre-halves this summer.
Lampard is keen on Brighton defender Ben White.
But the Guardian says Chelsea have to sell at least one of their four centre-backs; Andreas Christensen, Kurt Zouma, Antonio Rudiger or Fikayo Tomori, before signing a new one.
The same report also suggests that midfielder Jorginho could return to Serie A side Roma to free up some more funds.
White spent last season on loan with Championship winner Leeds and is ready to make his mark in the top flight.
