The Huddersfield boss was understandably delighted as his side beat Leeds on Saturday afternoon.
David Wagner couldn't hide his delight as Huddersfield Town beat Leeds United 4-1 in their Yorkshire derby on Saturday afternoon.
The emphasis was on the home side going into the clash, with Leeds having won their last three Championship games on the bounce.
But, after Stuart Dallas gave United the lead, it was all Huddersfield - and Wagner celebrated wildly on the Elland Road pitch at full-time.
The result leaves Leeds 13th in the league table, although it's done wonders for Huddersfield's standings.
Indeed, Wagner has taken Huddersfield up to 16th in the table with the convincing three-goal win. Now, the Yorkshire side are just two points behind Leeds.
The home fans were understandably livid after such poor defending allowed them to concede four times. The away end, however, was on cloud nine.
