After losing both Romelu Lukaku and Timo Werner in the last month, the Blues are little short on depth in the attack department at the moment.
The Daily Express reported that the Blues are now looking to sign Barcelona duo Frenkie de Jong and Pierre-Emerick Aubameyang.
The Catalan giants are still aiming to offload players in order to reduce their wage bill, with a couple more players reportedly expected to come in.
De Jong is reportedly still undecided on his future and there remains the issue of the wage reduction and the €14million of unpaid wages.
Aubameyang, meanwhile, has been linked with a move to the Stamford Bridge to reunite with Thomas Tuchel who he worked under at Borussia Dortmund, although reports suggests he is keen on staying at the Camp Nou.
Barcelona coach Xavi Hernandez admitted he is not sure what will happen with De Jong, who was a second-half substitute in the draw with Rayo Vallecano.
“No, Frenkie de Jong is not a substitute. I don't know what will happen with the market," he told reporters after the game, as per Fabrizio Romano.
“I can guarantee that if he stays, he will be important for us”.
