Arsenal could be set to replace Bacary Sagna, with reports suggesting that the Premier League leaders are tracking AC Milan defender Mattia de Sciglio.

30-year-old Sagna joined the Gunners from French outfit Auxerre in July 2007 and has given six years of excellent service to the club as first-choice right-back.

However, the France international's current contract is set to expire at the end of the 2013/14 campaign and it appears increasingly likely as if he will be allowed to depart North London this summer.

Losing such an influential and experienced defensive stalwart would certainly come as a blow for long-serving Arsenal boss Arsene Wenger, who will presumably be keen to draw up a contingency plan in the event that Sagna does indeed depart the Emirates Stadium.

It appears as if Wenger is already doing just that, with talkSPORT claiming that Arsenal are monitoring De Sciglio.

Successfully acquiring the 21-year-old Italy international could prove somewhat problematic, however.

Given his seemingly enormous potential, Serie A giants Milan are understandably reluctant to part with De Sciglio and would reportedly be looking for a fee of at least £10 million if they were to sell.
