Sunderland confidence delights Martin O'Neill

A "delighted" Martin O'Neill praises his "dangerous and confident" Sunderland side after they knock Arsenal out of the FA Cup with a 2-0 win at the Stadium of Light.

Kieran Richardson's defelected shot gave Sunderland an early lead, while Alex Oxlade-Chamberlain's own goal doubled the score late in the second-half to send the hosts through to the sixth round.
