DC: John Stones
Still a top target for Chelsea in January, £40m-rated Everton centre-back John Stones is one of the best young players in Europe in that position and could be the ideal replacement for John Terry.
DC: Marquinhos
Another outstanding young defender on Chelsea’s radar, PSG starlet Marquinhos, 21, is a £30m target for the Blues this winter and could be a great long-term purchase.
MC: Nemanja Matic
Brought back to Chelsea from Benfica in 2014, Nemanja Matic has been a superb signing and can be first choice in defensive midfield for many more years to come.
MC: Paul Pogba
Widely regarded as the best young player on the planet, 22-year-old midfielder Paul Pogba is a £70m target for Chelsea and a move could be on the cards this January.
