Scholes, Giggs, Neville & Van Der Sar will all play in the 2009-10 season. Less appearances than this season probaly but they will play. Giggs is the only one imo who stands a chance of playing in the 2010-11 season.
edit* I think for the purposes of the 5+6/6+5 ruleplayers from Rep of Ire should count as British.
FIFA found a loophole earlier in the year that means it could come to frution as well (european working law made the 6+5 rule illiegal).
