Yesterday, former England captain and current Match of the Day pundit Alan Shearer took to Twitter to celebrate the 20 year anniversary of his move from Blackburn Rovers to Newcastle United.
The £15 million move - a world record at the time - saw Shearer return to his hometown club in July 1996. Famously, though, it also saw the striker turn down the chance to sign for Sir Alex Ferguson and Manchester United.
Almost inevitably, then, Shearer's attempts to bring back the happy memories of signing for Newcastle were hi-jacked by some United fans who wanted to gloat that his decision ultimately cost him a bucketload of silverware.

The increasingly outspoken Geordie wasn't having any of it, though - singling out one particular Red Devils fans and trolling him with the oldest trick in the book when it comes to United fans.
First, the original tweet sent out by Shearer on Saturday afternoon...
Describing it as the "biggest and best decision" of his career, and including the #noregrets hashtag, the Premier League's all-time top goalscorer did leave himself open to some cheap shots about the fact he failed to win a single trophy with Newcastle whilst Man United racked up the honours.
The former England number nine has had to deal with similar put-downs for several decades now, and he wasn't about to sit back and let 'James Nicholson' attack his decision.
Instead, Shearer went for the classic approach used by many football fans when arguing with United supporters - question why they support the Old Trafford club despite not being from Manchester.
As a truly global brand, and one of the most successful clubs on world football, United have often been accused by their rivals of having a lot of 'bandwagon fans'.
So, whilst Shearer's response mightn't have been the most original anyone has ever seen, it will certainly have been met with a few laughs by fans of other clubs. It might not make him too popular the next time he visits the Theatre of Dreams, however.
