Derby boss Steve McClaren hailed his victorious side after they knocked West Brom out of the FA Cup.
Tom Ince and Darren Bent struck inside four second-half minutes to record the Rams' first FA Cup victory over a higher tier side since 1986 and seal a 2-1 win.
They cancelled out Matt Phillips' opener to surprise the Premier League club and secure Derby's first triumph over a top-flight team for eight years.
McClaren's side have lost just once in their last 12 games and are also seventh in the Sky Bet Championship, and the manager was delighted with their efforts at The Hawthorns.
