British and Irish Lions prepared for fiery welcome from Western Force in first Australian tour match British and Irish Lions players head to a training session in Perth. BRIAN O'Driscoll says "ruthlessness" will be key for the British and Irish Lions to break their 17-year series drought in Australia, but coach Warren Gatland believes winning could also come down to his men not biting at Aussie provocation. The Lions had only been on the ground in Perth a matter of hours yesterday when the first prediction of on-field feistiness emerged, courtesy of scrappy Force halfback Brett Sheehan. Sheehan, who will run out against the Lions tomorrow night at Patersons Stadium, said the Force would provide a bruising welcome for the tourists in a potentially "fiery" match. After Owen Farrell reacted to a Schalk Brits punch in Hong Kong, Gatland told his players to keep their cool if attacked or harassed; which duly pricked up the ears of Sheehan. Gatland stressed they wanted to stay disciplined. We want it to be extremely physical and for them to know they've been in a battle. If it gets fiery, that's good. Gatland would prefer the fireworks only occur before kick-off. The message we will be saying to the players is sometimes at this level, you might need to take one for the team. It's about keeping your discipline," Gatland said. O'Driscoll, named skipper of a strong side to take on the Force, returns to the city where he made his Lions debut in 2001 in a 116-10 walloping of WA. The "buzz" of pulling on the jersey remains as strong for the Irish centre but the satisfaction of winning the series is what is driving him. The Lions haven't won a Test series since 1997.
