The Gunners needed a win to return to fourth place with a single Premier League game against Everton on Sunday, but Newcastle did a “spur” of great service at St. James’s Park.
White, returning from a hamstring injury, turned Jolinton’s pass into his own goal in the second half, and Guimarães added a second late when the Magpies dominated on the side of Mikel Arteta.
The Spurs will travel to Norwich City on the last day, knowing that the point will almost certainly take them to the Champions League next season due to goal differences, and Chelsea are guaranteed to get into the top four and the injured Arsenal look doomed to Europa League.
The Gunners started shakily, and Aaron Rumsdale was lucky not to score Miguel Almiron an early goal if he held the ball too long after a reverse pass.
Dan Byrne blocked a sketch on Bucaio Sacco’s goal, but the Magpies continued to dictate, and Remsdale made a great save to his right to deny Alan Saint-Maximin after the French winger cut to the left at full slope.
Arsenal lost Takehir Tamiasu due to an injury before the break, and Newcastle defender Fabian Shar was forced to leave the field at the beginning of the second half, which landed hard after a header when he was caught by Eddie Nketi.
It was no surprise when Eddie Howe’s side took the lead in the 56th minute, when White did not allow Callum Wilson to reach the end of Joelinton’s canopy, but fell into his own net.
Wilson headed over the crossbar and struck a blow repulsed by White before the brisk striker approached the incredible goal from a distance that passed nearby.
Guimarães eliminated the knife at Arsenal when he was on hand to refuel the free ball five minutes after Rumsdale rushed to frustrate Wilson, and only Arsenal goalkeeper’s sharp save prevented Ryan Fraser from adding a third.
