Arsenal are interested in Sporting Lisbon fullback Marcos Rojo.
A Bola says Liverpool have sent scouts to check on the Argentinian international - who can also play at centre-back, with Brendan Rodgers keen on bolstering his back-line this summer.
But they will face competition from the Gunners - who are looking for a central defender as Thomas Vermaelen could leave the club at the end of the season.
