The former Spurs right-back left last summer for Atletico Madrid to rekindle his career.
And his performed well under Diego Simeone, whose intense training methods suit the ex-Burnley star.
But it is at Tottenham where Trippier will most likely be best remembered, though he had to earn his chance to play in the first-team.
He initially signed from Burnley for just £3.5m but was back-up to Kyle Walker.
After he moved to Manchester City, Pochettino felt comfortable Trippier could stand up and take his place - which he did successfully.
"When we got promoted [at Burnley] I only had a year left on my contract. I could have left on a free transfer after a year in the Premier League but I didn't feel that was right," he told The Beautiful Game podcast.
"So I signed a new contract which had a release clause of £3.5million if we got relegated. I'd had a taste of the Premier League, playing in every game.
"Then when a team like Tottenham come in for you it's hard to say no.
"Even though I knew Walks was there at the time I felt I had to take that next step and play as high as I can for as long as I can because you always want to play at the highest level.
"Then I made the move, and you can't turn Tottenham down. I knew it would be difficult."
One theory being bounced around is that Kane is past his peak due to the number of injuries he has sustained.

Furthermore, Pochettino supposedly told the forward to stop running in a bid to save his body, but Trippier has debunked this.
"No I wasn't [privy to hearing that]. Not at all. It does annoy me that people are saying that about H," he said.
"I'll give you a great example. People say about his injuries but the prime example is Danny Ings, who I used to play with. I think he's had four ACL injuries but you look at him now and he's flying. You can't write anybody off and especially H.
"How can you write him off? It just baffles me. Everybody gets injured but it's just laughable that the media or anybody can write him off. He could play at 50 per cent and still score goals.
"He's the best finisher I've seen, probably him and Jermain Defoe in training. H is great. He's the best pro I've ever come across. He doesn't drink. Top professional on and off the field.
"He does everything right. He will score goals wherever he is. I've got no worries about H."
