Olly Barkley believes England must tackle Samoa on Saturday with brains rather than brawn.

The Bath star, recovered from his torn hip abductor, starts for the first time alongside Jonny Wilkinson at inside centre.

He will share the responsibility for making the play in an encounter which England almost certainly must win if they are not to suffer the ignominy of becoming the first champions in rugby World Cup history to exit at the group phase.

Barkley's route to success centres on denying Samoa targets for their infamous crash tackles.

He said: ''They're an incredibly physical side so we have to give ourselves more time on the ball.

''The last thing we want is boys arriving on the pass when Henry Tuilagi is running straight at you. Depth is an issue. timing of the run. We don't want to give them anything massive to hit early on to let them get their tails up.

''We are going to try to move them around. Rugby is a very physical game but we don't want to be in a complete crash, bash battle with them.

''We're looking not to give them solid targets to hit which is what they really enjoy.''

Barkley is in no doubt the Samoans hit higher and harder than all other opponents having felt the muscular bulk of teammate Eliota Fuimaono-Sapolu in training at Bath.

But he also knows that it can be their Achilles' heel.

''You know the way they play the game,'' he said. ''If someone wants to fly in and take my head off and we get a penalty in front of the posts I'd take that and the three points.''

There has been much rumination at England's Trianon Palace base this past week to try to finger the source of the underachievement which culminated in the record 36-0 defeat to South Africa.

Barkley and Wilkinson at least should provide England with more direction and hopefully creativity, especially considering Barkley's performance at number ten against the United States was arguably England's best individual display of the tournament. They also ensure England's kicking game will be heavier and more precise but, following the failure to score tries in three of the last four games, it is the attack which has been the main source of concern.

Barkley said: ''We're looking at spreading options across the field. We feel our attack has been overly compressed the past couple of games, which makes it easier for teams to defend. We're working on having more options across the field on Saturday.

''It is obviously something which will take time but it something we are striving for.''

Do England have enough time?

''Probably not,'' said Barkley with commendable honesty. ''But what choice do we have?''
