Both players have been transfer-listed by Chelsea, though are yet to find themselves a new club.
Rosenior said: "I will have conversations with them. We're in January, as you know.
"Raheem's had an outstanding career. I've got huge respect for him. Axel is someone I've really, really liked as a player for a long time.
"Honestly, I have to have a conversation with them. I have to have a conversation with the club. I'm being genuinely honest. I literally have got to work through a list of priorities. I will do in the next few days."
On any incomings this transfer window, Rosenior added: "The first conversation I had with the guys (Chelsea management) was I want to assess the most important players, which are the ones who are here. Normally you get good surprises if you give people a chance.
"I had some really, really good surprises in the game against Charlton. Yes, we're in January, and yes, we want the club to be as successful as possible in the short term.
"But I also think sometimes the answers lie within the building and not outside. So I'll make a decision on that with the guys. Probably later in the week when I've seen everyone."
