And "Manchester United Football Club is going to win the Premiership" sounds to me as incorrect as "Manchester United is going to win the Premiership"
No matter what justification you use, "<football team> is..." will sound wrong to english speakers in the UK, Aus, NZ and a couple of other places (bar the person higher up in this thread who says they never notice it :))
"Manchester United is going to win", or "Scotland has no chance", Argh!! I've no real reason to hate this, but it just feels wrong!
