And even more impressively, our flying winger is the third-youngest player ever to reach that tally of games.
Steve Perryman, our all-time leading appearance holder, played his 300th game for us aged 23 in 1975, while Glenn Hoddle did likewise in 1982, a week after his 25th birthday. Aaron has reached his 300th appearance at the age of 25 years, 293 days.
'Azza' joined us from Leeds United in July, 2005, and made his debut against Chelsea a month later on August 27. Since then, he has featured in 221 Premier League games for us, scoring 24 times, and played 79 cup matches, scoring four goals.
Legendary former players Robbie Keane (306), Len Duquemin (307), Ossie Ardiles (311), Bobby Smith (317) and Dave Mackay (318) are next in his sights.
Andre Villas-Boas has been full of praise for the influential winger. “Aaron has been in excellent form and he’s such a responsible player," said Andre at The Hawthorns. "He’s a big influence in the dressing room as well."
