It is three years to the day that Manchester United striker Robin van Persie was given a guard of honour at The Emirates by his former club Arsenal.
United had clinched the 2012/13 Premier League title days earlier, with a win against Aston Villa at Old Trafford.
This led to Arsenal respectfully giving the champions a guard of honour in their next game, however humiliating it was for them to do so.
It was cruel on them because the man who inspired United to the title was the striker they sold to United the previous summer, cashing in on Robin van Persie for £24 million with one year remaining on his contract.
For that one season alone it was worth it for United, with Van Persie finishing the season with the golden boot and a title winner's medal which evaded him at Arsenal.
Gunners fans had hoped the humiliation would spur the club on, and in the transfer market they have been more aggressive, signing Mesut Ozil and Alexis Sanchez, but went back to old ways last summer.
They are still looking for their first title since 2004, while Manchester United are now trailing them in the race for fourth spot, with Van Persie sold last summer to Fenerbahce.
