Mikel Arteta has the utmost respect for Jose Mourinho.
The two head coaches were appointed at their respective clubs midway through the season, and will face off against each other for the very first time in Sunday's north London derby.
And Arteta is expecting Tottenham Hotspur to play with an 'extra edge' thanks to Mourinho.
"They have had some ups and downs but overall you can clearly see what he wants to bring to the club. He manages the energy, the momentum and establishes a really strong culture in every football club," our head coach said.
