Gloucester centre Trinder scored two tries to take his tally to six in six games for England this season and feels that the team are peaking at the right time.
England booked a place in the semi finals of the IRB Toshiba Junior World Championship as they clinched their third win of the group stages.
England will now face South Africa in the semi finals whilst New Zealand will face Australia.
Trinder said after the game:
"We've gone game by game and we're getting better game by game. Hopefully the more linebreaks we can achieve the more we can link up and score and that's making us a more threatening team."
"In the first two games against Scotland and Japan in the first 20 minutes we've been very slow and it's taken us a long time to get out of the blocks."
"Against Samoa we scored two tries in the first 10 minutes going forward. We've got some big ball carriers like Calum Clark and Carl Fearns and the backs were clicking so we looked pretty good."
"South Africa will be a massive challenge. It's the one we were expecting to come through from that group. Sure it'll be a big, physical South African team; good at running, good at kicking, equally effective doing both."
"There's definitely a belief that we can win this now. Coming out of the Six Nations we were very down. But ever since we started training for this tournament we've believed we can win it if we come together."
"We've only given up two tries - 14 points - in the three games and if we can keep that up with our attack we'll be fine."
Fly-half Billy Burns was named Man of the Match after the 35-14 European Rugby Challenge Cup victory over Stade Rochelais on Thursday evening, and was full of praise for all his team mates for the win after a short turnaround.
Gloucester have been in good form in recent weeks, but Backs Coach Tim Taylor knows that the Cherry and Whites will have to be at their best on Thursday evening (kick off 7:45pm) against a Stade Rochelais side flying high this season.
Speaking to GRTV after the bonus point win over Bristol, back row Lewis Ludlow revealed that despite a tricky first half, Gloucester backed their skills to come through, a faith that was evident in a strong second half showing.
Willi Heinz scored Gloucester's second try as the Cherry and Whites overturned a disappointing first 40 minutes and 0-6 half time deficit, to earn a 26-18 Aviva Premiership victory over Bristol Rugby on Saturday.
Gloucester's much changed side had to overcome conceding an early try on Thursday evening, but responded in style to down Stade Rochelais by 35 points to 14 in the European Rugby Challenge Cup and set up a mouthwatering return fixture next weekend.
After taking 11 points from their last three games in the Aviva Premiership, including bonus point wins against Wasps and Bristol, Gloucester will be looking to continue their good form when they welcome La Rochelle to Kingsholm.
