It was widely reported that Chelsea were set to have a quiet January transfer window, but that could now change.
According to The Telegraph, the club are now looking to sign a new centre-back this month and have been linked with Rennes' Jeremy Jacquet and Como’s Jacobo Ramon.
Former manager Enzo Maresca was keen for the club to sign a new central defender last summer following Levi Colwill’s ACL injury, but had his request turned down.
Speaking ahead of their Premier League clash with Brentford on Saturday (January 17), Rosenior has provided a transfer update.
When asked about January signings, Rosenior told reporters on Thursday: "I think if we do, it needs to be the right player. We need to be patient.
“I want to assess this group. It's really, really important to me. I like to give the players I work with a chance to show good surprises. We still have time.
“We have conversations every day, myself and the board, about potential transfers, both out and in, but at the same time, I need to focus on the players in the building.
“If I feel it's the right time or the right player, then we'll make that decision."
