Atletico Madrid goalkeeper Thibaut Courtois is wary of AC Milan striker Mario Balotelli going into their Champions League clash.

Balotelli hit a long range screamer for victory over Bologna on Friday.

"I haven't studied him closely yet," confessed Courtois.

"We know he's a great player. He has scored a goal from long distance. We need to be careful with our defending, but our coach is aware of that."
