Kieran Tierney is 'set to be allowed to play' for Arsenal against Man City - prompting a similar demand from Celtic over Ryan Christie.

The pair were forced to self-isolate after coming into 'close contact' with Covid-19 stricken Stuart Armstrong on international duty.

The Gunners' medical team challenged the 14-day isolation period, and Scottish Sun claim they have won their bid to have KT available for Sunday's game.

That will spring the Hoops into action who will likely demand Christie be available for Rangers under the same circumstances. Celtic were furious when the Scottish government forced their player to isolate for a fortnight despite sending back two negative coronavirus tests.

The Hoops are already without Hatem Abd Elhamed and Nir Bitton who did test positive for the virus, while Odsonne Edouard is a major doubt for the big game tomorrow afternoon after a positive Covid-19 test while with France under-21s.
