While the news of Emery's arrival came as a surprise, it did not take long for Arsenal fans to find some common ground with their new boss.
Gunners fans are delighted with past quotes from Emery, where he talks about Mourinho.
When Real beat Valencia 1-0 in 2010, Mourinho was complaining about referees after the game.
"Mourinho's stance is that of a crybaby," said Emery after the game to reporters.
"We have reasons to draw up a list with errors and to make a public complaint for every time we have been adversely affected, but we don't."
