Arsenal could be busy in the transfer window before it closes on Thursday, having identified Ricardo Rodriguez as a solution to their problems at left back.
The Daily Mail claims that Milan defender Rodriguez will be targeted by Unai Emery amid an injury crisis which could see Sead Kolasinac and Nacho Monreal both miss the start of the new Premier League season.
Kolasinac is certain to be out of the Gunners' first game against Manchester City on Sunday, having picked up a knee injury in last week's match against Chelsea in Dublin. He is likely to be missing for up to 10 weeks.
Monreal has not featured for Arsenal in pre-season, having returned to training with a knee injury that has kept him out of training. The Spaniard will return to full training this week but he is a major doubt for the City game.
Ainsley Maitland-Niles is likely to step in at left back but Emery wants Rodriguez to be his more permanent solution.
However, Milan are reluctant to sell the Swiss full back and Arsenal would have to cough up £30m to prise him away from the San Siro.
Rodriguez was one of Milan's better performers last season, having joined the club from Wolfsburg 12 months ago, and Gennaro Gattuso does not want to see him leave at this stage of the summer.
Arsenal have already strengthened their defence significantly this summer, bringing in Stephan Lichtsteiner from Juventus and Sokratis Papastathopoulos from Borussia Dortmund.
With Laurent Koscielny also sidelined with an injury that will keep him out until November at the earliest, it could be a very unfamiliar backline which starts at the Emirates on Sunday.
