Arsenal manager Arsene Wenger has praised Mesut Ozil for his lack of ego ahead of the Gunners' Champions League trip to Borussia Dortmund.
The North London club take on the Germans at the Westfalenstadion tonight in Group F of the competition.
Wenger believes that Ozil's selflessness has benefited the team following his summer move from Real Madrid.
"[He has brought] technical quality, vision and his absolute desire to play collectively in a very strong way," the Frenchman told the club's official website.
"He is a player who has only one master, that is football. He does what the game demands, his ego does not stand in the way of his game, all the great players have that."
Arsenal head into the match above Dortmund and Napoli in the standings on goal difference.
