The Arsenal head coach, Unai Emery, refused to be drawn into the reasons behind the decision to leave Henrikh Mkhitaryan at home for the Europa League match against Qarabag.

Diplomatic tensions exist between Azerbaijan and Mkhitaryan’s native Armenia following a long-standing conflict over the disputed Nagorno-Karabakh territory.

Mkhitaryan did not travel to face Azerbaijan Premier League side Gabala while with Borussia Dortmund in 2015, although he was told by Uefa that he would be granted a visa if we wished to make the journey. It is understood the same agreement would have applied this time around but that the club decided it was not necessary to undertake any application on behalf of the player.

The Qarabag coach Gurban Gurbanov claimed Arsenal had “saved” Mkhitaryan and were “afraid” of the pressure exerted on him by playing in front of a 68,000-capacity crowd at the Baku Olympic Stadium. Emery, though, would not go into depth on the issue, despite being repeatedly asked about Mkhitaryan’s absence by the Azerbaijani journalists at his pre‑match press conference.

“He cannot travel here,” Emery said. “We are here, the players with the best mentality and preparation and possibility to play tomorrow.”

Pushed on the Nagorno-Karabakh issue, Emery was keen to keep everything football-related. “My work is football,” he said. “I respect each person, I respect each people, I respect each culture, I respect each country. But I don’t know each situation in every country. For me, he cannot play tomorrow. There is respect for Mkhi and respect for you. Today we are here with the opportunity to play well.”

Emery brought a strong 21-man squad to Baku, including the likes of Mesut Özil and Alexandre Lacazette. He did, though, leave Pierre-Emerick Aubameyang at home along with Aaron Ramsey and explained the reasons behind it.

Asked about who had not made the 2,500-mile trip, Emery replied: “I explained first, for Mkhitaryan, why he cannot play tomorrow. Monday and Tuesday, Aubameyang was sick and he cannot travel to play tomorrow. Aaron Ramsey asked me if he can stay in London because his wife is pregnant and they are waiting on the doctors.”

Emery made several alterations to his side for the opening Group E win against Vorskla Poltava and is likely to shake things up again here. He did confirm that, with Petr Cech out for a month with a hamstring problem, Bernd Leno will start in goal.
