Jose Mourinho took the 24-year-old to Chelsea in the summer on a free transfer, but the Portuguese has now been replaced by Avram Grant and Sidwell was not in the 16-man squad at Manchester United on Sunday.
Coppell said: "I would fully anticipate that we will supplement the squad in January. I want good players and Siddy is a good player. He´s one of many I would love to bring here."
