England head coach Stuart Lancaster views Sam Burgess as a centre rather than flanker and will only consider him for the World Cup as a midfield option.

Burgess, who switched codes in October, played his best rugby as a back row for Bath last season including a run of six starts in the number six jersey that culminated in the Aviva Premiership final.

The 26-year-old’s success as a destructive blindside flanker appeared to end the debate over what position he should fill following a sluggish start to his union career.

England's line-out requirements, however, and the removal of Manu Tuilagi from World Cup contention on disciplinary grounds have compelled Lancaster to restrict his thinking on Burgess to the centre.

“We’re into the rugby stuff now and I had a long conversation with Sam about his position. For two reasons we see him as a centre,” the head coach said.

“In the back row we need our sixes to be effective in the line-out and there are some big players in our line-out calling structure.

"Tom Wood, for example, is the third most thrown to forward when he's played and James Haskell we've also used quite a lot. Tom Croft is nearing fitness now as well.

“We’ve lost (hooker) Dylan Hartley and with him some experience when the line-out is a big part for us. It would be a real stretch for Sam to be competitive in that position.

“Also, Bath have used him as a forward but his effectiveness has been in the middle of the defensive line and as someone who takes the ball to the line as a carrying threat.

“Without Manu in the backline, we need options that give us physicality. We’re confident from what we’ve seen that he’d be capable of competing at centre.

“Centre is where he’s been running with us and that’s where we’ll see him training right until the final 31 are selected.

“But it’s a competitive position when you see the options we have in the position.”
