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."
Ahead of Friday evening's Aviva Premiership fixture away at London Welsh, Head Coach Laurie Fisher told the local media that he feels that Gloucester are making improvements each and every week but that there's still plenty of work to do.
Speaking to GRTV on Monday night, Pete Buxton was thrilled with the spirit shown by the Gloucester United squad as they overturned a twenty-one point deficit in the second half to overcome Bristol Rugby.
