The Arsenal forward has fallen massively out of favour among fans in north London.
The 26-year-old joined Arsenal exactly a decade ago as a highly rated youngster. He came with bags of pace but not much else, with Arsene Wenger hoping to take his raw athletic talent to the next level via the right coaching.
Or so Arsenal fans thought. Ten years on, there has been no evidence of coaching, no evidence of change and not a hint of any actual improvement.
Indeed, Walcott remains the same pacey forward who runs at defenders but can't do anything different. His finishing is hit and miss and his decision making & football brain so often appear non existent.
After Arsenal's 3-2 loss at Manchester United on Sunday afternoon, it was as though the whole fanbase had rounded on the 26-year-old. Pundits slammed Walcott's anonymous display and supporters expressed their frustration at just how little the England man has learned since he moved to the capital.
And that begs the question: is Walcott the Premier League's most disappointing player of the last decade?
In terms of how consistently the Arsenal man lets his fans and team-mates down, there are few who could match him. Sure, he isn't the top flight's worst player, while others could be more disappointing for shorter periods of time.
But Walcott has produced so, so little with the Gunners. Without his speed, would he even be a footballer at all...?
