Tottenham Hotspur sign teenage Celtic academy player
The promising forward scored 15 goals for Celtic's under-16 team in the 2024/25 season.
Glancy, who joined Celtic at the age of six, is adept at playing off the right wing and in central areas.
He will start at Spurs as a first-year scholar in the under-18 squad.

Several Celtic youngsters, including Ben Doak, Aidan Borland, and Rocco Vata, have moved south of the border in recent years.
Meanwhile, two of Celtic's academy graduates, Dane Murray and Colby Donovan, played in the club's Champions League playoff defeat to Kairat Almaty on Tuesday.
Murray came on in the 75th minute, replacing Kieran Tierney, while Donovan substituted for Anthony Ralston in extra time.
Both players performed well, but Celtic were ultimately knocked out of the competition on penalties.
Manager Brendan Rodgers said: "It's hugely disappointing, and I really feel for the supporters that travelled all the way to be here, the effort and the commitment that they've shown to be here.
"We're bitterly disappointed for them as well as ourselves because the Champions League is a wonderful competition and we've seen that last year, we've seen the progress.
"But yeah, we would just have to, as we always do, we have to stick together as a squad and as a team and reflect on this, and we've got a huge game at the weekend.
"So yeah, it's a tough one to take.
"We didn't do enough over the two games."
