The 'Arsenalisation' of Emirates Stadium is an ongoing process. And perhaps the most striking change so far has been the imagery on the stadium's outside walls depicting 32 Arsenal greats 'embracing' the ground and its fans.

As part of Arsenal Football Club's 125th anniversary, we are taking a look back at the famous names who now adorn Emirates Stadium. From the men who helped build a legendary Club to our modern-day heroes, we pay tribute to each in our Heroes Together series.

Next up is David O'Leary, the center back who made a record 722 appearances in 20 years with the Club.

Watch our FREE video feature to learn some key facts about the player and hear from former teammates Perry Groves, Kenny Sansom, Nigel Winterburn and Ray Parlour.
