Gary Lineker believes Arsenal have already shown they are going to be Manchester City’s main challenger for the Premier League title.

The Gunners claimed a 1-0 victory over Tottenham Hotspur on Sunday in the North London Derby.

Gabriel Magalhaes was on the score sheet for Arsenal to claim their third successive win away from home against Spurs in the Premier League.

That means Arsenal are two points adrift of leaders Man City who have a 100 percent record in the top flight so far after their win over Brentford at the weekend.

Arsenal are due to meet Man City in the Premier League this weekend after taking on Atalanta in the Champions League. Going into that clash at the Etihad Stadium, Lineker believes the Gunners will be the main challengers for the league title against Pep Guardiola’s side.

“It’s already looking like Arsenal v Manchester [for the title] again,” said Lineker on The Rest is Football podcast.

Lineker went on to praise Arsenal’s defensive performance against Spurs, in particular centre-back duo Gabriel and William Saliba. Speaking about Gabriel, Lineker explained why the Brazilian is a vital member of the Gunners squad.

“It wasn’t a great game or a great spectacle actually,” Lineker said. “I expected it to be a bit more end-to-end, but Arsenal are so hard to beat. They defend so well, they really do.”

Lineker added: “We often talk about [William] Saliba but that partnership with Gabriel is very strong. Gabriel is a warrior, isn’t he? He’s a player you’d really want on your side, and he does chip in with the odd goal.”
