Liverpool's 1-0 victory over Premier League title rivals Arsenal on Sunday was testament to their hard working character, said boss Arne Slot, who praised his side's mentality given the influx of new faces and a difficult early-season schedule, Reuters reported.

The champions struck an early-season blow at Anfield against an Arsenal side who suffered their first defeat of the campaign in a game that was more grit than gloss, thanks to Dominik Szoboszlai's stunning free kick in the 83rd minute.

The Reds head into the international break with a perfect record after wins at home to Bournemouth, at Newcastle United and now Arsenal, who spent 260 million pounds ($351.23 million) in the close season in a bid to dethrone Liverpool.

"I'm most pleased with the team's mentality," Slot said. "We've had to bring quite a lot of new players in," according to Reuters.
