with plenty of highlights and great goals, that ultimately ended in disappointment. And now, it’s time to give it another go – except this time it’s under the watchful eye of “Europa League Master” Unai Emery.Emery’s accomplishments in this competition are perhaps the stand-out achievements of his career. As Sevilla manager, the Spaniard managed to win the competition in 3 consecutive seasons – an undoubtedly impressive achievement.Now, in his first campaign as Arsenal manager, he will have to draw from his previous successes in an effort to bring the Gunners back to Europe’s premier tournament – a tournament they have competed in during 19 of the last 20 campaignsThe first opponent of this campaign is Ukrainian side FC Vorskla Poltava. In the 2017-18 season, the club finished third in the top division for the first time since the 1996-97 season, booking their place in Europe. The last time Vorskla competed in the Europa League was in 2011/12 when they were knocked out of a group containing Hannover 96, Standard Liege, and FC Copenhagen.Vorskla have lost four of their five away matches in the league this season – including a heavy 4-1 defeat to European regulars Shakhtar Donetsk. That being said, they’re not in bad form, having won their past 3 domestic matches on home turf, and currently sit in a respectable 5th place after 8 games. The game is - fortunately for Arsenal - taking place at the Emirates Stadium, meaning travel will not be an issue for this contest, which will hopefully leave the side in better shape to face Everton on Sunday. On the pitch, perhaps Arsenal’s biggest downfall this season thus far has been their defensive solidity, and it is an area they will need to be wary of. In terms of attack, on-loan from Shakhtar, Vorskla forward Vladyslav Kulach poses the visitors main threat. The 25-year-old has scored two goals in six appearances this season, and is highly-rated in the Ukrainian Premier League. The opening Europa League fixture comes at a time for Arsenal where it appears that the new manager is beginning to find his stride following 3 victories in the past 3 games. Within the side, this match may throw up some interesting team changes for the Gunners, with perhaps the most notable being the likely inclusion of Bernd Leno in goals for the first time since he made the move to north London in the Summer. The general consensus upon the German’s transfer was that he would be installed as 1st choice goalkeeper at the club immediately, but this has not been the case. Petr Cech has remained as Arsenal’s number 1, and as such, will likely be rested for this midweek tie. This will give an opportunity for Leno to take the spotlight and stake his claim for a starting berth in the league.Or, perhaps, rather, it would be in Leno’s best interest to avoid the spotlight with Arsenal being undoubted favourites to win this match on home soil, it may be mishaps that bring attention to the new stopper. If he can offer an assured performance, then that would be a positive going forward. Other new signings Stephan Lichtsteiner and Lucas Torreira may also start the match, making it an interesting spectacle for fans to see the new players beginning a competitive match.While he did not start the most recent match against Newcastle United, Henrikh Mkhitryan was one of Arsenal’s stand-out plyers in his previous European campaign with the club, and will likely begin the match.
