Arsenal manager Mikel Arteta said he has 'dealt with' winger Willian's trip to Dubai, but did not reveal if the Brazilian will be dropped for Sunday's Premier League trip to Leeds.
Willian was pictured on Instagram at the Nusr-Et steakhouse in Dubai with celebrity owner Nusret Gokce, more commonly known as 'Salt Bae'.
Under coronavirus restrictions in the England, international travel is not permitted apart from for special purposes such as work or education.
However, the UAE is not on the UK's quarantine list and the 32-year-old Brazilian has been able to return to training this week.
"Whatever happens with things we don't expect, we will try to resolve them internally," Arteta said at his pre-match press conference on Friday.
"That's been dealt with and explained. We had a conversation and I explained what I was expecting.
"For every player there are a lot of personal factors at the moment."
Arteta has had to deal with a series of issues over the international break as Mohamed Elneny and Sead Kolasinac tested positive for coronavirus when with their national teams.
David Luiz and Dani Ceballos are also reported to have had a training ground altercation.
And Gunners' captain Pierre-Emerick Aubameyang had to spend a night on an airport floor with his Gabon teammates as they were delayed getting through customs in Gambia.
