Ball has to be inside the area, not the keeper. Like everywhere else on the pitch, it is the position of the ball that matters.
Has'nt seen any conclusive images yet, but i really feel he was harsely done by with such a marginal decision.
Giving the winner of the FA cup a CL spot would change it's status quickly .
Imagine Wigan or Bradford in the UCL though, would be a spot wasted.
No chance they would win it if it actually had any signifcance.
