Ally McCoist believes Arsenal manager Mikel Arteta "deliberately" acts out on the touchline to motivate his players and Gunners fans.
Arteta has been criticised for his animated behaviour on the touchline this season, which has included overzealous appeals at refereeing decisions. The Spaniard hit the headlines again after Arsenal's 4-2 win at Aston Villa last Saturday for appearing to mock the referee.
Arteta has been called an "embarrassment" by Richard Keys and a "clown" by Chris Sutton for his touchline antics, but McCoist does not have a problem with them. He believes the manager's behaviour has helped turn the Emirates into a "completely different stadium".
