England goalkeeper Fraser Forster does not know if he will still be at Celtic when they next play in Europe.
Norwich captain Sebastien Bassong has signed a new two-and-a-half-year contract.
The 26-year-old former Italy Under-21 international, who has made only six appearances for the Blucerchiati this term, joins bottom side Siena in their bid to survive in the top flight.
A statement on acsiena.it read: "Nicola Pozzi is a Siena player. The striker, born in Santarcangelo di Romagna on June 30, 1986, arrives on loan from Sampdoria."
Pozzi signed for AC Milan as an 17-year-old before enjoying successful loan spells with Napoli and Pescara. A prolific five-year stint with Empoli followed with Samp paying 5.2million euros for his services in August 2009.
