25-year-old Chelsea playmaker Oscar is almost certain to leave Chelsea in January after Chelsea accepted a huge bid for the Brazilian from Chinese side Shanghai SIPG. The fee is believed to be around £52-60 million.

Ex-Arsenal player Martin Keown has warned Chelsea against selling Oscar mid-way into the season because he believes Chelsea will be left with a weaker squad if Oscar leaves now.

“I think his departure would weaken Chelsea’s cause – and you question the ambition of the player,” Keown told Daily Mail.

“Even though he is not playing at the moment, the 25-year-old would be moving away from the best league in Europe.

“Oscar is surely well paid as it is at Chelsea but with a transfer fee of £52 million, the club will no doubt happily take the pot of gold.”
