Finishing second in the Premier League would usually be an excellent achievement for most sides - but not Arsenal.
Despite being favourites to lift the title last season, the Gunners slumped to a high yet disappointing finish, with Leicester City crowned champions.
Fans have since demanded that Arsene Wenger makes a number of world-class signings at the Emirates Stadium this summer, but so far only Granit Xhaka has arrived for £30 million.

What was meant to be an exciting transfer window has quickly turned into a frustrating one, and it would seem Per Mertesacker shares similar views.
The German centre-back fears Arsenal's lack of transfer activity could see them struggle to keep up with their rivals.
According to The Sun, he said: "The way last season went, we were quite lucky to finish second. We turned things around at the end but it was kind of a miracle we finished runners-up.
"What really disappointed us was that Leicester were able to take advantage of all the other big teams suffering and we couldn’t do the same.
"Of course, those big clubs will be stronger this time. That’s what I expect as they’ll start the season with a lot of new players.
"A lot of transfer business has already been done and it won’t be easy for us this time, especially with all the signings going to the other clubs.
"So we also need to be stronger and I am looking forward to seeing how well we compete for the title with not a lot of signings and a lot of young players."
Mertesacker's claim that Arsenal might enter the new season with "not a lot of signings" will worry fans, but it's important to remember that Wenger has pledged to splash the cash this summer.
And perhaps Riyad Mahrez will become his second big-name signing of the summer, with reports suggesting the Algerian has decided on a move to north London worth somewhere in the region of £35 million.
Ironically, it's Mertesacker who faces the greatest threat of being replaced at Arsenal, with fans desperate for a successor to be found for the much-maligned 31-year-old.
