New Arsenal boss Unai Emery arrives in England boasting history with Manchester United manager Jose Mourinho.

Emery used to manage Valencia and came up against the Manchester United manager in 2010 when he was in charge of Real Madrid.

Los Blancos won the tie 1-0 but the result didn't stop Mourinho criticising the referee.

Mourinho's actions didn't go down well with his opposition coach.

"Mourinho's stance is that of a crybaby," said Emery. "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."
