The period between breaking into the first-team squad and establishing yourself as a key member of the side can be extremely difficult for some prospects.
Some, such as Bukayo Saka, manage to make the step up rather quickly but for others the process can take years and even then they may not be successful.
Joe Willock and Reiss Nelson currently find themselves in something of a predicament, with neither player having featured prominently so far this season.
Willock has played 176 minutes in all competitions, while Nelson has been restricted to just 80 minutes, with neither player getting onto the pitch in the Premier League.
Last season Willock amassed 43 senior appearances for Arsenal but he has now fallen down the pecking order due to the signing of Thomas Partey and the return of Mohamed Elneny from loan.
Nelson, who also had a spell out through injury, has been impacted by the signing of Willian and knows that he faces a major challenge in terms of getting into the side.
The Europa League, then, could well be hugely important for both Willock and Nelson this season as they may receive game time that could help them to persuade Mikel Arteta to give them further chances.
Both players have featured heavily in the Europa League previously, but now the competition is of major significance to them.
Emile Smith Rowe also falls into this category although he is likely to be eased back slowly following his latest injury.
Nelson in particular has the quality to make an impact but it will be intriguing to see how this situation plays out and whether he and Willock are eventually able to break into the Premier League side.
With Arsenal having a large squad, it will be a challenging task, but the Europa League represents a big opportunity for them to prove their worth.
