Chelsea boss Frank Lampard admits two midfielders could be on the move in the coming days.
Kenedy is in talks with Sassulo, while Tiemoue Bakayoko is set to return to Monaco.
Lampard said: "There is a possibility of some movement, with Bakayoko and Kenedy."
On facing Sheffield United, the manager also remarked: "They have started well. I was very impressed with them last season, the job Chris has done can't be underappreciated. He feels deeply about the club and I felt that last year. I look forward to going up against them.
"You have to give credit where it's due. It is where they caught the eye last season and I enjoyed the tactical battle.
"It gives you a lot of threats. In terms of the Premier League, we will see if they adapt slightly and how people adapt to them. There is not just a tactical edge, but a physical edge and that might have grown slightly. I like the style of letting last season's players have a go."
