Sunderland and Chelsea's Premier League meeting at the Stadium of Light produced plenty of talking points, but two penalty decisions quickly became the centre of attention. With both sides fighting for crucial points, the referee's calls at either end of the pitch had a significant impact on the contest.

While one appeal from Chelsea was dismissed after a VAR check, Sunderland were awarded a spot-kick following a contentious challenge inside the box. Here's a closer look at both incidents and how they shaped the game ahead of the international break.

Cole Palmer penalty appeal : Why did Chelsea not get a spot-kick?

Chelsea's first major penalty controversy arrived in the 24th minute when Cole Palmer went down following a challenge from Sunderland's Luke O'Nien. Palmer had produced some impressive footwork to create space and drive towards the penalty area, getting past substitute Jules Ahoka, who had come on after captain Granit Xhaka suffered an injury.

However, O'Nien stepped across Palmer's path with his left leg, making contact and bringing the Chelsea attacker down. Despite the appeals, referee Jarred Gillett allowed play to continue. The incident was subsequently reviewed by VAR official Nick Hopton, who backed the on-field decision because the contact was deemed to have taken place outside the penalty area.

Although Palmer's momentum carried him into the box before he fell, the incident did not result in a penalty for Chelsea.

Brian Brobbey penalty incident : Why did Sunderland get a spot-kick?

Just 11 minutes after Chelsea's unsuccessful appeal, the controversy shifted to the opposite penalty area. Sunderland striker Brian Brobbey got the better of Chelsea defender Levi Colwill as he attempted to drive into the box, with both players appearing to hold onto each other during the tussle.

Brobbey had his left arm against Colwill's back, while the Chelsea defender held the striker's shirt with his right hand. The contact continued as the Dutch forward entered the penalty area. As Brobbey turned, his right foot appeared to clip his left, causing him to lose balance and tumble to the ground. There was also uncertainty over whether Colwill made contact with his heels.

Chelsea players immediately protested the decision, but referee Gillett pointed to the spot. Enzo Le Fee stepped up and converted the penalty to put Sunderland ahead, giving the hosts a lead they would not surrender.

Colwill was substituted at half-time, with Chelsea midfielder Moises Caicedo dropping into defence for Xabi Alonso's side. However, the tactical adjustment did little to change the visitors' fortunes as they struggled to seriously threaten Sunderland in the second half.

Chelsea eventually suffered their fourth defeat in eight Premier League matches, while Sunderland secured a crucial 1-0 victory at the Stadium of Light. The result helped the Black Cats climb off the bottom of the table after losing five of their previous six league games and going eight matches without a win.

Premier League releases official statement on Cole Palmer penalty decision

Following the match, the Premier League Match Centre released an official explanation of the decision not to award Chelsea a penalty after O'Nien's challenge on Palmer.

The statement read: "The referee’s call of no penalty to Chelsea was checked and confirmed by VAR. VAR: 'Confirming the on-field decision of play on, any contact with Palmer occurs outside the penalty area.'"

Ultimately, the two penalty incidents became defining moments in a match that had significant consequences at both ends of the Premier League table. The victory also offered some relief to under-pressure manager Regis Le Bris as Sunderland headed into the international break with three important points.
