Cameras caught the exchange between Arsenal manager Arsene Wenger and Liverpool manager Kenny Dalglish, and it didn't seem very sportsmanlike.

After a controversial ending that saw two penalty kicks in the closing minutes, the match had come to an end after Dirk Kuyt slammed home the equalizer goal as the last play of the match.

As the managers made their way closer to the field in what often ends in a customary hand shake, Dalglish, with a smile on his face, had his hand extended for a shake.

But an irritated Wenger waved it off.

Dalglish's smile quickly turned, and it appeared that he said, P**s off.

In a match with title implications that ended in high drama, perhaps poor etiquette is somewhat understandable.
