Chelsea goalkeeper Djordje Petrovic set for unlikely Premier League transfer as Blues cash in despite impressive Strasbourg loan

The Blues stopper is on his way to Sunderland for a deal worth around £21.5 million ($29m), according to journalist Sacha Tavolieri, as the Mackems look to boost their squad on their Premier League return.

Petrovic had a fine loan at Strasbourg last season but Chelsea have decided to cash in rather than keep him on their books. The Serb made 31 appearances for the Ligue 1 side, who qualified for the Conference League.

Petrovic's departure would leave Robert Sanchez and Filip Jorgensen as the two leading goalkeepers on Chelsea's books, though there is some suggestion the move is not as advanced as initially reported. The Guardian's Jacob Steinbergclaims Petrovic still has interest from elsewhere.

It remains to be seen whether Chelsea make a move for a new goalkeeper ahead of the start of next season, having been linked with AC Milan's Mike Maignan. For now, their focus is on Saturday's Club World Cup quarter-final against Palmeiras.
