Antonio Rudiger and Tiemoue Bakayoko have both liked a post from Chelsea’s new kit manufacturers Nike on Instagram.
The two are expected to become Chelsea players next week.
As reported last week, manager Antonio Conte wants to sign at least three new players before the start of pre-season.
Recent reports have claimed that Juventus full-back Alex Sandro will be next.
American player turned pundit Janusz Michallik has claimed at the start of the week that the Brazilian has already agreed personal terms to move to Stamford Bridge.
"I think it's [Alex Sandro to Chelsea is] a done deal," he said.
"There's some question marks for me at Chelsea. I love him, I have no idea why Juventus would get rid of him.
"Obviously they have got rid of some big, big players and they've proven to everybody they can still move on. If you look at Pirlo, Tevez and Pogba, they're still capable.
"I think he's a tremendous player in that back four."
