Celtic gave 13-year-old Karamoko Dembele his debut for their Under-20s team in Monday’s 3-1 win over Hearts – and Rangers fans took to Twitter to remind their rivals of Islam Feruz.

The youngster was rewarded for his stunning development with a place on the bench, which saw him face players up to seven years his senior.

The forward replaced Jack Aitchison in the 81st minute of the game and had a cameo nine-minute spell in his first Under-20’s appearance.

The international break presented Dembele with an opportunity to make the step up with Ross Doohan, Anthony Ralston, Mark Hill, Regan Hendry, Calvin Miller and PJ Crossan all away with the Scotland Under-19s.

Rangers fans took to social media to remind their rivals of Feruz, who left Celtic to join Chelsea in 2011 and is still awaiting his debut aged 21, currently on loan in Belgium with Royal Excel Mouscron.

Here are a selection of their messages on Twitter:

Dembele has already been compared to Barcelona superstar Lionel Messi at his young age after his incredible balance, pace and goal-scoring ability.

Like Feruz the starlet is said to have already caught the attention of some of the world’s biggest clubs, but it is understood that he is settled at Celtic.

In other Rangers news, Joey Barton has revealed that he wants to prove everyone wrong at Ibrox following his three-week suspension from the club.
