Both clubs are looking to strengthen their defensive options and the Croat full-back is high on their list of targets. Manchester City spent over £100m on full0backs alone last summer but injuries struck and now Pep Guardiola is in the hunt to ease pressure on his squad.
Vrsaljko is frustrated by his lack of opportunities at Atletico since he moved there from Sassuolo in 2016. Sixteen appearances, mainly in domestic and European cup competitions, last season suggested Vrsaljko would challenge for the right-back spot this campaign.
Instead, Juanfran’s grip on the full-back slot has not diminished and despite featuring in the Champions League for the Rojiblancos, Vrsaljko has made more appearances for his country than his club.
The Spanish media reports that the renewed interest from last summer sparked the decision in the Croatia international who has won 27 caps to date. Previously, Atleti had rebuffed any offers from clubs for the full-back.
However, the right-back is concerned that the lack of playing time is putting his international place under threat.
Cup-tied in the Champions League, Vrsaljko may prefer to move to Napoli where his opportunities for first-team football may include Europa League football with the Italians likely to drop out of the premier competition at the group stage.
