There's absolutely no point in getting frustrated - Bruce only allows Brits in, as he's only bothered about training ground bants. This was never going to happen. Bruce's checklist - is he English? Is he British, at least? can I pronounce his surname? Does he like stotties? Is he a 'good laugh'? Is he cheap? Position and ability don't tend to feature highly.
He's also applys an argument from ignorance approach.. That being 'oh well he's had games for man united, so that means he's got to be class'.
