Arsenal will take on Chelsea on Wednesday evening in the Europa League final, a game which has been somewhat overshadowed by the controversy surrounding where it is to be played.
The Baku showpiece is not only the Gunners' chance at a first European trophy in 25 years, but also their final opportunity to play Champions League football next season.
The clash in Azerbaijan will be the 198th fixture between the two London clubs, and it's a fixture that has produced some wonderful moments of the years.

This was early on in Arsene Wenger's first full season in charge at Highbury, and Gunners fans knew they had a special side to finally challenge Manchester United's reign of dominance.
However, when Gus Poyet and Gianfranco Zola cancelled out Dennis Bergkamp's superb brace, Arsenal needed to find a winner to keep the pressure on Sir Alex Ferguson's side.

Following goals from Dan Petrescu and Tore Andre Flo, and with only 15 minutes to play, the Gunners looked down and out.
That was until an extraordinary performance from Nigerian forward Nwankwo Kanu, who scored an incredible hat-trick to single-handedly drag Wenger's side to a memorable win at the Bridge.
The winner was particularly special, as after he rounded the goalkeeper, he somehow found the net from the tightest of angles to give Arsenal a dramatic 3-2 win.

However, Claudio Ranieri's side had other ideas, even after a first half Jose Antonio Reyes goal made progression to the semi finals near impossible.
