The Italian has said that he is content with his squad but has not ruled out the possibility of a late arrival as the Fulham striker is linked with a move
With Radamel Falcao out injured for several months, Monaco have been linked with numerous offensive arrivals - including the veteran Bulgarian - and while the Italian coach is content with the options at his disposal, he did not rule out a possible late swoop for the Fulham forward.
"There is nothing definite," he said at a press conference on Friday when asked about any late movement in the January window.
Valere Germain has been enjoying a revival lately in the Monaco side, and Ranieri praised the youth product's recent displays.
"Valere Germain played a good match against [Olympique de] Marseille, in which he scored, and he deserves his chance," the Italian said. "If he is called, I know he will respond. He will stay with us."
Anthony Martial, meanwhile, has impressed to such an extent since his summer move from Olympique Lyonnais that Monaco recently gave the teenager fresh terms, and Ranieri is pleased to have him back from injury.
"He has overcome his ankle problem and has trained well all week," the former Chelsea boss said.
Meanwhile, Monaco have also been linked with a move for Toulouse centre-back Aymen Abdennour as the January transfer window prepares to slam shut.
