Trippier curled a set-piece past Croatia goalkeeper Danijel Subasic to give England the lead in their World Cup semi-final, though the Three Lions went on to lose 2-1 after extra time.
As England prepare for Saturday's Nations League opener against Spain before facing Switzerland in a friendly three days later, Trippier told reporters: "I'm not going to lie to you, I've watched it back about 100 times.
"Obviously, I enjoyed that moment but even now it still hurts that we got beat. But I did watch it back about 100 times I'm not going to lie to you."
Trippier followed up his World Cup goal by scoring a free-kick for Spurs in their Premier League win over Fulham last month, and he is now sharing set-piece duties at club level with Christian Eriksen.
"To be fair to Christian we had a bit of banter about free-kicks and stuff as soon as we walked in [for pre-season training]," he said.
"In the last few games we've been sharing them out a little bit because of the opposition and which delivery can hurt them the most.
"It's all about the confidence at the time. Everyone knows how good Christian is at set plays and delivering a ball but against Fulham I just felt confident, first game back, and I said to him 'do you mind if I take this one?' He said 'no problem' - and I managed to score it."
Trippier has established himself for club and country thanks to his consistent performances on the right flank but, asked about the possibility of being dropped by England manager Gareth Southgate, the 27-year-old replied: "Obviously, all the boys are doing well here and for their clubs, so that's the manager's decision, if I play or don't play.
"Every opportunity on the playing field I try and do my best 100 per cent to show the manager that I want to play and just keep improving but it's the manager's decision at the end of the day on who he selects.
"So, if I don't play I'm not going to be disappointed, I'll help my team-mates, but I'll be training as hard as I can to make sure I am picked."
