Both players, who joined on Deadline Day, are in contention to make their debuts against Leeds United on Saturday.
Nigeria international Chukwueze, who joined the Cottagers on an initial season-long loan from AC Milan, reunited with his new teammates on Thursday after returning from international duty with Nigeria.
Kevin, an exciting addition from Shakhtar Donetsk, has spent the past week settling in at Motspur Park, having had no international commitments.
“We believe the profiles of Chukwueze and Kevin will add to what we’ve been looking for in those areas of the pitch,” Silva told club website.
“With Adama, Harry Wilson and Alex Iwobi, they’re going to be our solutions for the wide areas of the pitch.
“Kevin has settled in well. He’s working hard to understand everything we need from him. He’s very young, 22-years-old, but he has the experience of playing Champions League and European games.
“The first time I saw Chukwueze and Jonah (Kusi-Asare) was yesterday, but Kevin is slightly different because he’s been with us for the last 10 days. Him and Chukwueze are going to help us.”
