Newcastle Falcons benefitted from the speed of Zach Kibirige and Marcus Watson in Sunday's win against Enisei, said director of rugby Dean Richards.
Kibirige, 21, and Watson, 24, scored six tries between them in the European Rugby Challenge Cup victory.
It was the club's first win of the season, following five defeats.
"The ability to change pace at full speed is something I've never had, but they've got it in abundance," Richards told BBC Newcastle.
"Those two boys have a lot of pace, a lot of ability and it's nice to have them back."
Kibirige's return to the Falcons side was a boost for Richards, after last season was cut short by a serious ankle injury suffered in his Premiership debut against Gloucester.
The England Under-20 international has worked on strength and conditioning during his rehabilitation in a bid to avoid further lay-offs.
"It comes down to what you've got between your ears," Richards said.
"He showed that in his try for England Under-20s against Wales, and went the length of the pitch.
"We know Zach has that, but it's about getting him back on the field which we haven't been able to do for a little while.
"Now he's back, he's out there, we're pleased, we're delighted.
