Chelsea have reportedly identified Paris Saint-Germain defender Marquinhos as a potential summer transfer target.
On the back of winning the Champions League in May, the Blues hierarchy are prepared to make a number of significant additions over the coming months.
Declan Rice and Erling Braut Haaland are allegedly regarded as the club's preferred additions, business which would cost in excess of £200m.
However, according to The Mirror, Chelsea head coach Thomas Tuchel is open to being reunited with centre-back Marquinhos.
Tuchel worked with the 27-year-old during his time at Parc des Princes and any transfer would see the player resume his partnership with Brazilian compatriot Thiago Silva.
Marquinhos has three years left on his contract, keeping PSG in a strong position with regards to his future.
