Arsenal have reportedly made enquiries for a trio of defenders ahead of the close of the summer transfer window.
Winston Reid, Matija Nastasic and Ron Vlaar are said to be the centre-backs being tracked by Gunners manager Arsene Wenger, who is looking to fill the gap left by the recently-departed Thomas Vermaelen.
Goal.com reports that West Ham United's Reid and Nastastic of Manchester City are Wenger's top targets, while a late move for Aston Villa's Vlaar could be on the cards should a move for the other two break down.
The same article claims that Arsenal's move for Sporting Lisbon midfielder William Carvalho has stalled, with the 11pm deadline for transfers to go through drawing nearer.
