Leeds United teenager Jack Clarke made his Championship debut in the club's draw with Brentford, coming off the bench in the second half.
For those who have seen Clarke perform for the under-23s, it was overdue, even though strictly speaking, the 17-year-old is well ahead of schedule.
Clarke was impressive for Leeds in pre-season and the former Manchester City academy talent looks like Leeds' brightest prospect.
He is a versatile attacker who can play as a winger, attacking midfielder or even up front.
At just 17 with Marcelo Bielsa as his manager, the shape of Clarke's career is still being moulded and the Argentine may have particular plans for the youngster.
The timing of his breakthrough is key. There is still some two-and-a-half months before the transfer window opens.
Leeds fans want owner Andrea Radrizzani to make one final push in the transfer market to strengthen the club's promotion challenge come January.
Clarke has a chance between now and then to show he can be a solution and save the club millions by stepping up as a first team regular.
He will have to be patient, as Pablo Hernandez's return from injury will limit his chances. When they come his way, he has to make the most of them.
