The retired midfielder feels his former Manchester United teammate does not reliably translate his fine club form to the international stage

The veteran was among several of the 'Class of '92' who assisted Ryan Giggs during the Welshman's spell as interim manager toward the end of the season but was not kept on as part of new boss Louis van Gaal's full-time coaching staff.
Scholes said he is working on his qualifications but has no particular job lined up for when they are complete.
"I am taking my coaching badge and willing to see what comes from it day by day," he said. "Nothing planned."
Of Van Gaal's new regime, Scholes remarked: "United needs to do what United does best, play attacking football.
"Players need to enjoy their football again so they can be their most creative and deadly."
