BRITAIN SOCCER EUROPA LEAGUE Unai Emery
Eintracht Frankfurt heaped more pressure on under-fire manager Unai Emery after coming from a goal down to beat Arsenal 2-1 in the Europa League on Thursday.
Pierre-Emerick Aubameyang opened the scoring shortly before half-time only for Daichi Kamada to grab a brace in the 55th and 64th minutes in front of disgruntled Gunners fans at the Emirates Stadium.
The defeat was Arsenal's first in the Europa League campaign this season and also means the Gunners are now winless in seven matches - the first time since 1992.
"Emery Out. No tactics, no formation, nowhere to hide," read some of the printed posters that emerged after the second goal as some of the home fans headed for an early exit.
Despite the mounting pressure on his job, Emery was keen to take the positives, telling BT Sport: "Today I think we improved.
"In the first half we had control of the game and we were winning 1-0 ... we lost control in 15 minutes of the second half and they scored two goals and then we couldn't change the result."
Emery, who did not discuss his future other than to say he was focusing on Arsenal's next match at Norwich on Sunday, added: "I am being positive but above all realistic.
"We are now well ... we are top of the group and we lost a very good opportunity to achieve the next round tonight, but we are going to take another in Liege."
In Kazakhstan, Astana came from behind to beat a youthful Manchester United side 2-1, benefiting from an own goal in the second half.
United defender Di'Shon Bernard, one of three teenagers who made their senior debut for the English team, deflected a shot by Antonio Rukavina into his own net in the 62nd for what proved to be the winning goal.
It was the first loss of the Europa League campaign for United, who had already secured a spot in the knockout stage.
Astana are last despite earning their first three points.
Jesse Lingard marked his first game as United captain with a low shot from outside the area for his first goal of the season 10 minutes into the game, which was played on an artificial surface.
Dmitri Shomko equalised for Astana in the 55th - the first goal United had conceded in the campaign - just seconds after another teenager Tahith Chong failed to hit an open net from close range at the other end.
Ethan Laird and Dylan Levitt also made their first start in a United team that had an average age of 21.6 years, including 36-year-old goalkeeper Lee Grant.
"Definitely (there are positives)," United manager Ole Gunnar Solskjaer said.
"Of course we're disappointed with the end result ... but some fantastic performances by the three young lads who made their debuts, all were excellent."
In Glasgow, Celtic defeated Rennes 3-1 with manager Neil Lennon opting to leave some of his top players on the bench, including Socceroo Tom Rogic.
Lewis Morgan, Ryan Christie and Michael Johnston were the goalscorers as Celtic maintained their unbeaten run in the competition and remained top.
Porto beat Young Boys 2-1 with a brace from Vincent Aboubakar while English club Wolves drew 3-3 with Braga.
Wolves led 3-1 after goals from Raul Jimenez, Matt Doherty and Adama Traore but conceded to Paulinho (64th) and Fransergio (79th).
However, the point was enought to secure a passage in the next round for Nuno Espirito Santo's side following Bratislava's 2-1 defeat to Besiktas.
