Manchester United took on Chelsea this afternoon with Louis van Gaal taking on Jose Mourinho in one of the most anticipated games of the campaign so far.
It was certainly a fixture that did not disappoint with Robin van Persie embracing his captain role for the day by smashing home a last minute equaliser - after Didier Drogba had given Chelsea a 1-0 lead.
But the game probably made some Arsenal fans sick.
Chelsea and United are undoubtedly two of Arsenal's main rivals for silverware this season. The fact that two former Arsenal captains will be leading them on their way to glory does not please The Gunners faithful.
Van Persie took the captaincy from Cesc Fabregas after the latter left The Emirates to join boyhood club Barcelona. But after one season he was on his way.
He decided to leave for United in order to get his hands on the Premier League title - which he did in his first season.
This summer Fabregas was offered back to Arsenal after Barcelona decided that he had not been a hit at the Nou Camp. However they decided not to bring him back to The Emirates and instead he has become an assist king at Chelsea - who are the favourites for the Premier League title.
And it is because of this that moments like the photo attached can happen. Robin van Persie and Cesc Fabregas having a pre-match hug - neither player in an Arsenal shirt.
Enough to make Gunners sick up and down the country.
