Ghanaian young forward Kwame Poku registered his second goal of the season in Peterborough United embarrassing home defeat to Derby County in the English League One.
Hat-trick hero Martyn Waghorn starred in a stunning Derby comeback as they roared to a 4-2 win at Peterborough.
The Rams found themselves trailing in the 23rd minute after a Peterborough United opener from a move started and finished by Jonson Clarke-Harris.
But it was one-way traffic from then on as the visitors went on an almighty attacking raid - scoring four times in 16 minutes against a Posh side who had only previously conceded twice all season.
Their charge was spearheaded by veteran forward Waghorn, who levelled with a coolly-taken volley from a Liam Thompson cross in the 29th minute before Eirin Cashin completed the turnaround with a 37th-minute header from ex-Posh man Nathaniel Mendez-Laing's delivery.
Waghorn, who returned to Derby for a second spell in the summer, then poked in a Mendez-Laing shot in the 40th minute to extend the advantage.
And the 33-year-old completed a fifth career hat-trick with his fifth goal of the current season - a classy curler on the stroke of half-time.
A miserable afternoon for Posh boss Darren Ferguson was compounded when he was sent off by referee Lewis Smith with 20 minutes to the end of the match.
Kwame Poku, who enjoyed the entire duration of the game, bagged a 90th-minute consolation for the hosts.
Newly-signed Ghanaian midfield-gazzer Tyrese Fornah made his debut for Derby County with a cameo appearance.
Poku has bagged two goals and two assists in five league matches for Peterborough United in the ongoing season.
