Harvey White made his full debut for Tottenham in their FA Cup victory at Marine a little over a week ago.
But now he has swapped life with the Premier League title-chasers for a crack at trying to win promotion with Pompey.
The teenage midfielder has moved to the south coast in a loan deal for the remainder of the campaign.
And he is hoping to make a positive impact as the Blues prepare for a hectic run of fixtures over the next few months.
White said: “I played in the Marine (FA Cup) game and got a call a few days later to say that Pompey were interested.
“Straight away I thought it was a great move for me and that I could learn a lot. I’m finally here and really excited.
"Hopefully I can stamp my mark and get on the pitch to help this team get promoted back to the Championship."
“This is my first loan and it’s going to be really challenging. I’ve been in a men’s football environment for around eight months now, but this will be different.
“I really love my set-pieces and look to keep the ball moving. I get a lot of assists and like to think I’m effective.
“There’s a game tomorrow and then one on every Saturday and Tuesday, so there are a lot of them coming up.
“Hopefully I can stamp my mark and get on the pitch to help this team get promoted back to the Championship.
“I’m looking to improve during my time here and see where it takes me because I want to play at the highest level.”
White netted a free-kick for Tottenham’s under-21 side when they were beaten at Fratton Park in an EFL Trophy tie in 2018.
He said: “It was a great memory and there were a few fans there that day. I love scoring and hopefully I can now do that for Pompey!”
