Uefa says it is “working to ensure” Arsenal’s Europa League tie with Vorskla Poltava will take place in Kiev on Thursday.
Uefa moved the game’s location from Poltava to the capital because of the introduction of martial law in several regions in Ukraine.
Earlier on Wednesday Vorskla vice-president Oleg Lisak said there was no guarantee the Ukrainians would play.
But the club later said it accepted the match would be played in Kiev.
The group stage fixture is due to take place at the capital’s Olimpiyskiy Stadium at 17:55 GMT on Thursday.
Vorskla tweeted: “Despite all the attempts of the football club to hold a match in Poltava Uefa has made its decision, and the game will take place in Kiev.”
The club also tweeted a picture of the team coach on their way to Kiev.
Arsenal manager Unai Emery said: “First, we need to respect Uefa’s decision because I think it’s not easy for Vorskla.
“Yesterday we were preparing for the first trip to Poltava and waiting in the evening for the last decision.
“It doesn’t change a lot to play here. In 90 minutes it is not a very big change. It is clear they are playing in Ukraine, not in their town, but they can also move their supporters to Kiev.
“In 90 minutes we want to do our work here.”
Uefa said: “The urgent decision of Uefa to relocate the match to Kiev was based on the sudden introduction of martial law and the uncertainty of the security situation in some parts of Ukraine and particularly given the extremely short timescale available to evaluate all existing risks.
“Uefa regrets the inconvenience the relocation of this match has caused to supporters and FC Vorskla.”
Uefa said it will continue to monitor the security situation in Ukraine.
