After a game of 'what could've been' against Manchester United, Liverpool are making some progress in Brendan Rodgers' new 3-4-3 system.
Sunday's 2-2 draw with Arsenal showed some promise from the system, particularly with how impressive Philippe Coutinho and Adam Lallana were in dropping into pockets of space behind Raheem Sterling in attack.
Yet it's still quite unbalanced; Lazar Markovic, a flying right winger, was used at left wing back, whilst Jordan Henderson was pressed into action at right wing back.
That's something that Rodgers may look to rectify in January, especially with Glen Johnson seemingly set for the Anfield exit either in January of next summer.
The 22-year-old Croatian is one of the best emerging right backs in Europe right now, and his performances for Serie A side Sassuolo have triggered interest from the likes of Juventus and Tottenham Hotspur.
Vrsaljko has experience playing right back, right wing back and on the right of midfield, and has honed his skills to the point where he is an all-round wing back who has the potential to be one of the world's best by the time he hits his mid-t-late 20's.
Reports suggest that Vrsaljko could be available for as little as £3m, which would be a bargain for Liverpool - who must sign an attack minded right back in January.
