The European governing body was heavily criticised for the meagre allocation totalling just 12,000 tickets given to the English teams.
But with the final taking place miles away in Azerbaijan’s capital Baku, supporters are now turning their back on the event.
Fans of both sides have been put off by rising travel costs, and the 5000-mile round trip it would take to attend the fixture.
UEFA could now be left red-faced at the prospect of not selling out the 69,870 capacity stadium.
The Gunners have sold half of their 6,000 allocation, whilst Chelsea have only managed to flog 2,000.
It was only earlier this week that Arsenal complained to UEFA about the proportion of tickets made available to them.
But now both sides will return their unsold quantities, with UEFA set to sell them locally instead.
23,000 fans are already said to be attending from the host nation.
The decision to hold the final in Baku has been met with widespread criticism, as obtaining visas has also become another stumbling block.
Arsenal’s Henrikh Mkhitaryan threw another spanner in the works, when he declared on Tuesday that he will not play a part in the match, for fears over his safety.
Ongoing political tensions between his native Armenia and the host nation for the final has proved to be a factor in his decision.
Gunners skipper Laurent Koscielny slammed UEFA for awarding Azerbaijan the final in the midst of such political unrest.
“I am not very happy,” Koscielny told BBC Radio 5 Live. “First because we need to leave one player here, because he can’t play in the final.
“I think UEFA needs to know about the different problems they can have with the politics in the country. When one country has a problem with another they should not give the final to that country.
“For us it is difficult because we want to have Micki with us. He is an important player for us.”
