Confused Robin van Persie goes towards wrong dressing room at the Emirates, gets guard of honor

With Manchester United sealing their 20th league title on Monday thanks to a Robin van Persie hat trick, the former Arsenal striker was set up for the best possible return to visit his former club on Saturday. Or worst, depending on your perspective.

When Van Persie arrived at his former home, his eight years in north London were clearly still very much ingrained in his head. A big smile on his face, Van Persie hugged and shook hands with Arsenal staff in the tunnel when he arrived in his Man United suit. He went towards the door to the home dressing room before catching himself and veering towards the away dressing room, slapping himself on the forehead once he realized his mistake.

Once Van Persie remembered which team he plays for, he lined up with his Man United teammates so the Arsenal players could give them a guard of honor. Arsenal supporters still working through feelings of loss and betrayal offered disheartened boos. Van Persie tried not to show emotion one way or the other.

UPDATE: After getting booked himself for a poor challenge on Per Mertesacker in the 28th minute, Van Persie was hauled down in the box by Bacary Sagna in the 44th minute. He scored the penalty to make even the score at 1-1 and did not celebrate. There were more boos.
