The year 2014 was viewed as one of the biggest in Arsenal's modern history.
It signalled the end of eight years of frugality, with the £260m Emirates Stadium debt finally paid off.
There was also the opportunity for Arsenal to agree new partnerships for their three main revenue streams; matchday, broadcast and commercial.
Arsene Wenger was the key man in all of it, keeping the club in the Champions League between 2006 and 2014 despite receiving little or no funding to buy players.

Big things are still expected of the Polish midfielder-turned-defender. However, loan spells at Birmingham and Walsall have done little to help the progression of the 20-year-old.
Currently on loan at Stevenage, the England U18 international could still have a bright future at Arsenal. But he needs to start matching the likes of Emile Smith-Rowe and Reiss Nelson.
A real unknown name. The Finish goalkeeper moved from his homeland when he was 16 and failed to make a senior appearance. He's now at Brighton after completing a free transfer this summer.
Imagine Paul Merson trying to tackle that surname. The Greek left-back was part of Arsenal's academy before moving to Brentford in 2016 - where he also failed to make a senior appearance.
