Rangers fans have poked fun at ex-Celtic star Kieran Tierney after a nightmare afternoon for the defender.

Tierney shared a photo before kick-off in today's derby wishing both the Hoops and his current team, Arsenal, luck ahead of their big matches.

The £25million left-back urged his ex-teammates to "get intae them" at Parkhead before sharing a COYG snap as the Gunners prepared to welcome Chelsea to the Emirates.

One said: "Thoughts are with Kieran Tierney at this time."

Another added: "It's been a bad day for Kieran Tierney."

One fan commented: "Cheer up Kieran Tierney."

A fourth said: "Kieran Tierney managing to lose two derby games in a single day without kicking a ball. Please RT to raise awareness."
