From the current situation, even Mertesacker and Koscielny return, Arsenal still need to add centre backs, because this position is really the Gunners' short board. Recently, Arsene Wenger has delineated four players, including the European Cup Jose Fonte.
The other three are Toprak, Kjaer and Mustafi. Toprak, aged 27, joined Bayer Leverkusen in the summer of 2011. His contract expires in the summer of 2018. His valuation is 20 million euros. Kjaer, 27, joined Fenerbahce last summer. Kjaer's worth is estimated to be 10 million euros. Mustafi is the closest to Arsenal. In the summer of 2014, after winning the FIFA Big Strength Cup, Mustafi joined Valencia. Arsenal is nearly getting him with 32 million euros.
Fonte became stablized until January 2010 after joining Southampton. This summer, he represented Portugal to have played the European Championship. In the four games of the playoffs, he played as the starter and helped Portugal to defeat France to win the European Championship. P.S. Don't hesitate to buy FIFA 16 Coins on www.imfifa.co.
