Bournemouth forward Antoine Semenyo, reportedly close to a big-money transfer, was at the heart of the action, providing two assists and conceding a penalty in a dramatic 2-2 stalemate against Chelsea.
Despite being on the verge of a lucrative switch, the 25-year-old attacker started for his club. He utilized his long throw expertise to great effect, creating scoring opportunities that were finished by Brooks and Kluivert.
Brooks opened the scoring just six minutes in, converting from close quarters after a dangerous long throw from Semenyo.
Chelsea responded and then took the lead after Semenyo fouled Estevao Willian inside the penalty area. Referee Sam Barrott pointed to the spot after consulting the Video Assistant Referee (VAR) monitor.
Cole Palmer stepped up and converted the penalty, finding the corner despite the goalkeeper guessing correctly. Enzo Fernandez then extended Chelsea's lead, firing a superb shot into the top corner after 23 minutes.
Bournemouth hit back almost immediately, as another Semenyo long throw was turned in by Justin Kluivert from close range just four minutes later.
Chelsea created further opportunities, but Bournemouth ended the first half strongly, testing goalkeeper Robert Sanchez with numerous attempts.
The home side's boss reshuffled his team at the break, bringing on James and Neto for Acheampong and Garnacho.
Early in the second half, a handball appeal against Malo Gusto was dismissed by the VAR official. Former Chelsea goalkeeper Djordje Petrovic then produced an excellent save to deny Estevao from distance.
The best chance of the second half fell to Enzo Fernandez in the 77th minute, but he blazed his shot over the bar from inside the box.
Palmer's withdrawal for Pedro was greeted by boos from a section of the home crowd as the manager's side sought control. Despite growing dominance in the latter stages, Chelsea could not find a decisive late goal.
Deep into added time, Unal connected with an Adli cross but sent his volley over the bar from a central position.
This draw extends Chelsea's poor run to only one win in their previous seven Premier League matches. For Bournemouth, the point does little to improve their own form, as they remain without a win in ten games.
