The France international midfielder, 23, is understood to be on United's radar and skysports.com are now claiming he is the Premier League champions' top target this summer. Nasri's reluctance to engage in contract talks with Arsenal until he is satisfied their transfer targets are of the required standard to mount a title push next season has alerted Sir Alex Ferguson to his possible availability. Despite being close to wrapping up a deal for Blackburn defender Phil Jones and Atletico Madrid goalkeeper David de Gea, amid widespread speculation Aston Villa's Ashley Young is also heading for Old Trafford, Ferguson's appetite for new signings has yet to be sated. Nasri is seen as an ideal replacement for the retired Paul Scholes, with the centre of the field an area United's management are keen to revamp with fresh talent. Inter Milan's Wesley Sneijder has been linked but Nasri, with just a season left on his existing deal, could be a more realistic deal to finance. Arsene Wenger would be loathe to lose one of his key men, especially given Nasri's exit would likely lead to other members of his squad questioning their own futures. However, United are now ready to test Arsenal's resolve to keep a player who has previously intimated he would be open to the prospect of moving to Manchester.
