The 17-year-old played 45 minutes of their first pre-season game, as a late Harry Kane winner gave the north London club the coveted victory.
But who is the youngster that could provide some much needed competition up front for Spurs? Here are five things to know about Tottenhams Irish prospect:
He Was Deadly Up Front at Youth Level
A two-in-three ratio is something that many professional footballers struggle to achieve, but with 20 goals in 30 games at youth level, Parrott has looked dangerous from the very beginning.
Not only can he score goals but he also creates them, with five assists to his name as well.
This goes hand-in-hand with his versatility, having the ability to play as a striker, a winger or a number ten.
His Stats Match Harry Kanes
As parrots go, one mimicking Englands best striker would be quite something! However, this Parrott seems to have what it takes.
The man from Dublins stats at Under-18 level match up well to Kanes from his time playing at that development stage.
Both produced precisely 3.6 shots per game and both fouled an opposition player 1.9 times per 90 minutes.
If anything, Parrotts performances were even more impressive than the England stars, registering 2.6 dribbles per game to Kanes 1.4.
Even the attribute that Kane is famed for, dropping deep to pass and assist with build-up play, is eclipsed by Parrott. The youngster registered 23.3 passes per game as opposed to Kanes 19.7.
Mauricio Pochettino Stopped Him From Playing for Ireland
Spurs boss Mauricio Pochettino held Parrott back from joining up with Irelands Under-19s for the European Championship in order to see what he could do in pre-season.
It seems Pochettino views Parrott as a potential option up front this season and has insisted on including him in the squad for Spurs pre-season tour.
The tour will be the first time that Tottenham play football since their defeat in the Champions League final to Liverpool, and the Argentinean is looking at all options to help them close the gap between themselves and the Premier Leagues top two.
He Is One of Seven Youngsters Involved in Spurs Pre-Season Preparations
Parrott is one of seven young players to be included in Mauricio Pochettinos pre-season plans.
The manager has also involved midfielders Jack Roles, Harvey White, George Marsh and Jamie Bowden who will compete with the existing central players and new signing Tanguy Ndombele for game time.
Winger Anthony Georgiou and goalkeeper Brandon Austin have also been brought into the fold for the tour, however, whether any of them continue with the first team in the regular season is yet to be decided.
He Has History on His Side
Tottenham Hotspurs academy has produced many successful talents in recent times, with Kane being their crowning achievement.
The likes of Oliver Skipp, Harry Winks and Kyle Walker-Peters can also be added to the list. The three are competing for spots in the Spurs first-team but the conveyor-belt of players didnt start there.
Tom Carroll has made a career for himself at Swansea City, while Josh Onomah has recently returned from a loan spell with Sheffield Wednesday.
If the past is anything to go by, Parrott can create a good career for himself within English football, but whether that is at the top level remains to be seen.
