Bournemouth boss Eddie Howe expects the tackles to fly tomorrow night against Southampton.
Southampton meet traditional rivals Portsmouth in the Carabao Cup on Tuesday, but Howe feels Bournemouth's games against the Saints are "gaining in everybody's focus".
"It should be a really feisty game, a really good atmosphere and an entertaining match," Bournemouth boss Howe told Sky Sports. "Southampton have started very well, too.
"It's gaining in everybody's focus. The more games we have, the more the rivalry will intensify I think.
"We've enjoyed the games against Southampton which have been tight and tough, from both clubs' perspectives. We're looking forward to another entertaining match."
