According to Spanish outlet Fichajes (via the Daily Star's Alex Wood), Arsenal and Roma are both "likely" to move for the Argentinian, although "Villarreal are desperate to keep hold of [him]," and will demand more than the reported £11.5 million the Gunners are prepared to offer.
Arsenal yet again fell short in their bid to win the Premier League in 2015-16 and need to make effective additions in the summer if they are to be title challengers next season.
The centre-back region at the Emirates is short on depth and quality, with Laurent Koscielny the only consistently reliable performer Wenger has to call upon.
