Szoboszlai curled a sublime set-piece past Arsenal keeper David Raya with seven minutes left at Anfield in a tense clash between the two leading contenders for the Premier League crown.
The Hungary midfielder’s gem was enough to seal a third successive league victory for champions Liverpool as Arsenal lost for the first time this term following consecutive wins.
The Gunners finished as runners-up behind Liverpool last season and the clubs have been engaged in an expensive arms race since the end of the season.
Liverpool’s Florian Wirtz and Hugo Ekitike and Arsenal’s Martin Zubimendi and Viktor Gyokeres had their chance to shine under the spotlight on Sunday.
None of the new additions dazzled. Instead it was Szoboszlai, deployed out of position at right-back, who delivered the defining moment.
Zubimendi fouled Curtis Jones 25 yards from goal and Szoboszlai stepped up with a masterful finish.
Liverpool, who have the only 100 percent record in the top tier, go into the international break in a familiar position on top of the table as they chase a record 21st English title.
“If you win against a team like Arsenal, who last season were such a good team and have strengthened so much, it is very positive,” Liverpool boss Arne Slot said. “In the end we needed a moment of magic. We will know at the end of the season what it’s worth.”
Arsenal must lick their wounds after a result that suggested their bid to end a run of three successive second place finishes is still a work in progress.
“At the end of the game, I said we have to find a way to win these big matches,” said Arsenal manager Mikel Arteta.
Earlier, at the Amex Stadium, City striker Erling Haaland marked his 100th Premier League appearance with his 88th goal in the competition since joining from Borussia Dortmund in 2022.
But the 25-year-old’s third goal this season wasn’t enough to help Pep Guardiola’s side bounce back from last weekend’s 2-0 home loss to Tottenham.
West Ham eased the pressure on boss Graham Potter with a 3-0 win at Nottingham Forest.
Potter had faced calls for his sacking after West Ham conceded eight goals in two successive top-flight defeats, then crashed out of the League Cup at Wolves.
Former Chelsea and Brighton boss Potter, who has only been in charge of West Ham since January, may have earned a stay of execution thanks to three goals in the last six minutes from Jarrod Bowen, Lucas Paqueta and Callum Wilson.
Aston Villa’s winless start continued with a 3-0 home defeat to Crystal Palace.
Jean-Philippe Mateta, Marc Guehi and Ismaila Sarr struck for the Eagles as Villa missed the presence of goalkeeper Emi Martinez.
The Argentine was absent from the Villa squad amid speculation he could make a transfer deadline day move to Manchester United on Monday. (AFP)
