I'm not trying to defend Giggs, he should have tried harder to make himself available more but....to an extent his career fell in the middle of two of the better periods of Welsh international football i.e. the Rush, Hughes, Saunders, Ratcliffe, Southall team and the recent and current Bale, Ramsey, Williams setup.
Giggs no doubt got a fair bit of pressure from his club manager when it came to international friendlies as Utd tended to be fighting on several fronts.
