Paris Simmons struck for the tenth time this season to earn the Rams' Academy team three points for the first time since October.

The 18-year-old netted his second in two games since the turn of the year as Derby took their tally to four points in a week.

Simmons robbed a United defender four minutes before half-time and finished well for the only goal of Saturday's encounter at Moor Farm.

Derby stood firm after the break to ensure that they held on to their advantage in a game of few chances.

Simmons had also been on target seven days previously as the young Rams picked up a creditable 1-1 draw away to Middlesbrough to open 2008.

They had closed 2007 with seven successive defeats - six in Group D of the FA Premier Academy League, and one in the FA Youth Cup.
