Finn Russell was on form from the kicking tee

Warriors led 16-3 at the break thanks to Flynn's try from a rolling maul and three penalties by Finn Russell.

With Fraser Brown in the sin-bin for a "no-arms" tackle, Dragons scored early in the second-half through a Sam Hobbs try and followed that up minutes later with a Jack Dixon score.

Prop Alex Allan's fine solo score restored Glasgow's advantage before a late Russell penalty sealed the win.

Speaking to glasgowwarriors.org after the game, Gregor Townsend said: "I'm delighted for the players, they have put in a lot of effort over the past two or three weeks with no reward and they'll feel better tonight on the journey home.

"In the first-half we really stamped our authority on the game. Maybe we missed a couple of opportunities to take points in the opposition 22 and then we had to deal with that yellow card, but I was pleased going into half-time.

"The next 15 minutes wasn't so good and we allowed the Dragons back into the game.

"But the final quarter was much better as we worked hard to get back in front then push to increase our lead. Our set piece work was really disciplined and the line-out and scrum functioned really well.

"The team have shown their character time and time again. Last week against Ulster was a really good example and tonight we had to dig deep with players who hadn't played much for us in recent weeks, with a couple more players making their debuts, and a few others coming back from injury.

"It was really pleasing but there is a lot to work on. Possession and territory won us the first-half but we have to be more clinical when we get close to the opposition try line."

Lewis Wynne made his second start and fifth competitive appearance for the Warriors, Matt Fagerson made his second appearance as a replacement and Djustice Sears-Duru and Robert McAlpine made their debuts from the bench.

The Glasgow head coach says it's great to see the young players grasp their opportunities when they come along.

He added: "I think the young guys in the squad have have really stepped up. Lewis Wynne worked very hard agan tonight and he's played every single game this season, including all the pre-season games. Nobody else has done that and he's been a big part of what we've done at the beginning of this season.

"Djustice (Sears-Duru) on his debut made an impact from the bench and Robert McAlpine and Matt Fagerson did well coming on at the end. These young players will get a lot of experience and we're pleased that they got stuck in.

"The experienced players also played really well though. I thought Sila (Puafisi) was strong at the scrum, Corey (Flynn) and Pat (MacArthur) both had good games at hooker and Josh (Strauss) had some vital carries at times to get us over the gainline. That was great to see and it was also great to see our new second-row combination of Jonny (Gray) and Rob (Harley) get through the game relatively unscathed. On Tuesday it didn't look as if Rob was going to be able play but he put in a big shift for 80 minutes.

"We'll need this selfless attitde throughout the next few weeks as we play another away game then go into our Champions Cup matches."
