Liverpool sent a scout to run the rule over Red Bull Salzburg defender - and reported Arsenal target - Martin Hinteregger during Austria's international friendly with Uruguay last week.
The Guardian reports how the 21-year-old centre-back is attracting interest from the Premier League after turning in a series of impressive performances at the Red Bull Arena.
Gunners boss Arsene Wenger is believed to be an admirer of Hinteregger, and is considering an attempt to lure him to the Emirates Stadium when the transfer window reopens in the summer.
With question marks surrounding the long-term future of Thomas Vermaelen in north London, the French tactician might be forced into the market to bring in additional cover for Per Mertesacker and Laurent Koscielny next season.
However, Arsenal will now face competition for Hinteregger's signature from Liverpool, after Brendan Rodgers deployed an Anfield scout to make a personal check on him in Klagenfurt on Wednesday night.
Hinteregger was pitted against Liverpool striker Luis Suarez on only his second international appearance, and emerged from the encounter with reputation in tact following a commanding performance at the heart of the Austrian defence, helping Marcel Koller's side earn a 1-1 draw with their South American opponents.
His physical nature and composure on the ball means the Red Bull Salzburg star should be well suited to the style of England's top-flight. All that's now left is for Hinteregger to decide where his future would be better served, at Liverpool or Arsenal, assuming he receives offers from both suitors in the summer.
