Chelsea came out on top in an open encounter at Dean Court after defeating hosts Bournemouth 4-1.
The Cherries made two alterations to the side beaten 2-1 at home to Liverpool last time out, with Marc Pugh and Lewis Grabban recalled, while Chelsea interim head coach Guus Hiddink was forced into a number of changes.
Asmir Begovic started in goal, with Thibaut Courtois suspended, while Jon Obi Mikel was deployed in central defence, and Nemanja Matic and Eden Hazard returned to the starting XI.
Five minutes in the Blues took the lead when Cesc Fabregas played a measured ball through to Pedro and he lifted a fine finish past the advancing Artur Boruc.
Seventeen minutes in Joshua King lashed a shot high and wide after latching on to a corner and Steve Cook also blasted over as another set-piece caused problems for Chelsea.
Pugh was next to hoist an effort over the crossbar, as the hosts continued to press, with Begovic then making a solid save from Grabban, before claiming a King header seconds later.
Grabban flashed a header wide from a ball in from the right, only for the visitors to strike again on the break, with a low Hazard effort from 20 yards somehow finding its way past Boruc.
However, the Cherries pulled a goal back almost straightaway when a corner from the right was headed home by Tommy Elphick, and Grabban then forced Begovic into a smart save at his near post.
Junior Stanislas crashed a shot over from the edge of the Blues area, before Pedro curled an effort a yard too high when he should have done better.
Early in the second half, Baba Rahman powered forward from left-back and Diego Costa came within inches of converting the low ball into the near post.
Charlie Daniels then made a superb block to deny Pedro following a corner, before the hosts made a double change, with Benik Afobe and Callum Wilson heading on to the field.
Stanislas was next to go close with a curling effort from 25 yards, only for the visitors to spring forwards and score a clinical third goal.
The outstanding Fabregas was again the creator when his weighted pass playing in Willian, who coolly lifted the ball over the advancing Boruc.
Right at the death Chelsea added further gloss to the scoreline when Hazard was on hand to convert after Fabregas and Matic did the set-up work.
