Transfer news: Mario Balotelli's agent Mino Raiola tells Sky Sports News HQ the Italy striker is happy at Liverpool
Mario Balotelli's agent has told Sky Sports News HQ the Italy striker is "happy at Liverpool" and gets on well with Brendan Rodgers.
Italy striker Antonio Cassano has left troubled Serie A club Parma after rescinding his contract.
Traore, who made his international debut as a 15-year-old, has long been on the Blues' radar and impressed during their pre-season tour of Asia, when the attacking midfielder scored a spectacular goal in an 8-1 thrashing of the Indonesia All Stars.
Chelsea were unable to sign Traore to a permanent deal until his 18th birthday last month, but the paperwork has now been completed.
"Traore, joining from Association Jeunes Espoirs De Bobo-Dioulasso, is a full international for Burkina Faso having made his debut in September 2011 a few days before his 16th birthday," a Chelsea statement read.
"He has 10 international caps and has scored once ahead of next month's World Cup qualification play-offs in Africa in which Burkina Faso face Algeria.
"In 2011 he helped his nation win the Africa Under-17s championship.
"An attacking midfielder, Traore was taken as a trialist on Chelsea's tour of Asia in the summer and played a part in all three games, scoring in Malaysia and in Indonesia."
Following his goal in Indonesia during the summer defender Gary Cahill was full of praise for Traore, saying: "He's a young lad, but I'm sure he's got a bright future at Chelsea."
