Ward-Prowse scores from spot after foul on Adams
Defensive mix-up allows Callum Wilson to score and seal win
Southampton 1-2 Bournemouth
Cedric Soares and Diego Rico have a little tussle on the Southampton backline. Rico thought he had been caught in the face and Soares didn't like his theatrics.
Rico responded to a finger waggling with a bit of an air swipe which just missed Soares' face. Bit naughty...
Southampton 1-2 Bournemouth
Jack Stacey is shown a yellow for a challenge on Ryan Bertrand after the Saints' man had continued his run into the box before his cut-back was intercepted.
Good advantage from the referee as Southampton still have the ball in a dangerous area.

Job done for Harry Wilson. He's being replaced by Ryan Fraser.

Oh, this would have been brilliant! Neat build-up down the right ends with a flick from Che Adams to set up James Ward-Prowse, who fires it over from long range.
Wasn't a bad effort!

The decision stands. No penalty for Bournemouth. Hmm, interesting one. There's definitely a shout there!

They are giving it another look. Cedric Soares did look like he caught Joshua King...

Bournemouth manager Eddie Howe turned away in disgust as referee Chris Kavanagh pointed to the spot - not so much at the decision to award a penalty but as he probably knew Steve Cook's clumsy challenge on Che Adams has thrown struggling Southampton a real lifeline.
Suddenly, the Southampton fans are noisy and sensing something.

James Ward-Prowse's free-kick is not too far away from the head of Jannik Vestergaard but the ball eventually floats into Aaron Ramsdale's arms.
Seconds later, Nathan Redmond cuts onto his left foot on the edge of the box but his effort flies wide and high.

Tony Pulis
Former Bournemouth manager on BBC Radio 5 Live
He's a great dead-ball striker. It's a great penalty. Game on.
James Ward-Prowse
Fired into the top right corner. No chance for Aaron Ramsdale. Perfect start to the second half from the Saints.

He didn't have to make the challenge, he should have let the ball go down the line. Cook has committed himself. It's a penalty.

Che Adams is brought down by Steve Cook in the box! Penalty to Southampton. Is this the lifeline they needed?

Dominic Solanke is allowed to run all the way into the box but he runs out of legs at the last minute.

Jon Matthews: Bournemouth's style of play is the perfect antidote to Southampton's. That said, a little better with the final ball, a little more clinical in the shot and a little more organised in defence and Saints would be on top. The margins in football are always fine.

That was Southampton's best move of the game. Free-flowing football, a good switch of play and they had numbers in the box.
