BETTING & MATCH ODDS
Arsenal are favourites according to dabblebet, with odds of 3/10 for the Gunners to win. Koln are priced at 8/1 to win, while a draw is available at 17/4.
While Arsenal will be forced to endure jibes as part of their participation in the Europa League, the reality is that the tournament represents an excellent opportunity for the club to book their place in next season's Champions League.
With the Premier League becoming increasingly competitive, top clubs are finding it difficult to qualify for Europe's leading club competition, but the second-tier Europa League has become a realistic alternative route, with the likes of Chelsea and Manchester United benefitting after winning the tournament in recent years.
Wenger's side have experienced some early wobbles in the 2017-18 league season, with the futures of Alexis Sanchez and Mesut Ozil also shrouded in uncertainty, but they can set the tone for the rest of the year with a convincing display in Europe.
Indeed, with a crucial derby clash against Antonio Conte's Chelsea coming in the league three days later, an emphatic victory at home to one of Germany's better teams will not only set them up nicely in Group H, but it will also give them plenty of momentum as they look to climb up the league table.
