Luke Moore, Roman Bednar, Abdoulaye Meite, Leon Barnett, Gianni Zuiverloon and Joe Mattock could all be set to leave the club, according to The Mirror.
Di Matteo is keen to sell the players in order to make a couple of new signings in January.
“We are all scouting all the time, we are always looking to improve the team,” he said. “With all transfers, you need a bit of luck. It’s difficult when you make a decision to bring a player in.
“If we stay injury free, maybe we’d like to add one more player that can give us an extra dimension – but they come at a price.”
