Arsenal defender Pablo Mari says that Liverpool's front three of Mohamed Salah, Sadio Mane and Roberto Firmino are the toughest opponents he has ever faced.
Mari signed for Arsenal on loan in January after shining with Brazilian side Flamengo, having previously been on the books at Manchester City.
It was with Flamengo that Mari faced off with Liverpool's trio of stars, with the Brazilian side meeting last season's Champions League winners at the Club World Cup.
And, in an Ask Me Anything session on Reddit, Mari revealed that his battle with that trio was the toughest of his career.
