Despite looking comfortable in possession for most of the first half, Atletico were restricted to half-chances and Raul Garcia's wasted a good opportunity when he headed straight at Christian Abbiati.

Balotelli was inches away from breaking the deadlock before the interval but he just missed the target with a curled effort.
