Chelsea have already held secret talks with Philippe Coutinho over a summer transfer from Barcelona, according to reports from Spain.
Coutinho has been linked with a return to the Premier League this summer after failing to live up to his potential since his switch from Liverpool in 2018.
The Brazil midfielder had hoped to secure a permanent switch to loan club Bayern Munich but the Bundesliga giants have decided not to exercise their option to buy.
Manchester United, Arsenal and Tottenham have all been linked with moves for Coutinho, but Chelsea have already spoken with the 27-year-old's representatives, according to Spanish publication Sport.
