It is an exciting time to be an Arsenal fan.
With new signings Alexis Sanchez and Mathieu Debuchy joining the likes of Mesut Ozil and Aaron Ramsey, there is a real buzz around the Emirates Stadium, and there will likely be more new arrivals to come.
For a few players, however, added competition for places may not be such good news. These three Gunners face a make-or-break season if they are to be successful at the Emirates in the long term.
Since he joined Arsenal in 2011, Jenkinson has shown the potential to be a good Premier League full-back. He has pace to burn and is an excellent crosser of the ball, but needs to work on his game defensively.
Jenkinson has been stuck behind Bacary Sagna for his entire Arsenal career, and when the Frenchman departed for Manchester City, it appeared that the 22-year-old could get his opportunity to be the first-choice right-back.
That will not be the case, however, as the Gunners signed Debuchy from Newcastle. Jenkinson will begin next season on the bench, and must take every opportunity that he can to prove to manager Arsene Wenger that he can earn the starting job in defence.
With interest from West Ham United already this summer, Wenger will be tempted to cash in next year if he doesn't believe that Jenkinson is capable of nailing down the position.
Gnabry faced a similar challenge to Jenkinson last season. He e was on the fringes of the first team and only really featured when injuries hit Theo Walcott, Lukas Podolski and Alex Oxlade-Chamberlain.
The German is an out-and-out winger, but will now be stuck behind the aforementioned trio, as well as Santi Cazorla and new boy Sanchez.
When he did play last season, Gnabry showed some flashes of real brilliance, and he undoubtedly has the potential to start for Arsenal.
A season on the bench, however, could spell the end of the road at the Emirates for the 19-year-old simply due to the competition for places at his position.
Opportunities to strut his stuff in 2014-15 could be few and far between, but Gnabry could force his way into Wenger's long-term plans if he takes the chances he is given.
Wilshere remains one of the biggest names in the Arsenal squad. He is a highly talented midfielder and has the potential to be a key man for both club and country for years to come.
When he first broke into the first team at the age of just 17, Wilshere drew rave reviews. Since then, however, the hype has died down and his progress has been hampered by injuries and inconsistency.
He was overtaken in the midfield pecking order by Ramsey last season, and Wilshere's best position may be in the number 10 role, which is currently inhabited by Ozil.
Next season the 22-year-old must show that he can perform at the highest level on a consistent basis, and that he can thrive in a deeper midfield role.
On top form Wilshere is a fantastic player and he could certainly help Arsenal lift the Premier League trophy in 2015 if he fulfils his enormous potential. He simply cannot afford to spend next season hovering on the periphery of the starting XI.
