Cook warns Gloucester are up for a battle

The Cherry and Whites hit rock bottom at home last weekend when they were crushed 29-8 rivals Saracens to leave them out of contention for the Aviva Premiership, lying in eighth place.
The defeat adds to their woes in Europe, where a home defeat to Edinburgh in round four leaves them five points adrift of Munster in Heineken Cup Pool 6 with two games to play.
