Josh Onomah showed enough against Aston Villa to suggest he can become a star.
Onomah had previously made cameo appearances in the FA Cup and Europa League, but this was a new show of trust from head coach Mauricio Pochettino.
The teenager was brought on with the score at 2-1, with Villa in the ascendancy, and the decision to bring Onomah on when they did was a big one by Tottenham.
Many managers would have chosen to bring on a defensive player to close out the game in such a scenario, or a more experienced player regardless of the tactical approach.
Onomah is an England under-19 international, but this was an entirely new experience for the youngster, and he flourished.
Onomah's performance showed just why Pochettino has such faith in him, justifying the decision to bring him on.
The 18-year-old was confident in possession, always looking for a pass, and when there was not one available, he was confident enough to run with the ball and shoot, with a late effort testing Brad Guzan.
He did enough to show that with regular football, he can translate his goalscoring appearances for Tottenham's under-18 and under-21 sides to the first team, and become a match winner.
Onomah is the type of attacking player who can make the breakthrough which Alex Pritchard has been denied this season due to injury, and deserves more chances.
It is likely he will feature on Thursday night against Anderlecht in some capacity, whether as a starter or on the bench, and while sensible to calm immediate expectations, long-term he could be a vital part of Pochettino's plans.
