The good news is Acheampong is not expected to be sidelined for an extended period.“He is recovering from a minor thing,” the Chelsea manager said. “He missed the fitness to be ready for today but we are expecting that he will be back after the international break. It’s a pity because he was in a good moment.”Potential return date: Saturday November 21, vs Leeds (H)Emi Martinez"He has made a great effort to be available but probably it was too rash, too risky [to be selected],” Alonso said.Emi Martinez is closing in on a return to action after jaw surgeryAFP/Getty“So he will use one more week, 10 days, to keep on training and get used to the mask.
