Egil Roger Olsen (born 22 April 1942), nicknamed Drillo, is a Norwegian former football manager and player.

Olsen was a successful player with 16 caps for the national team, earning the nickname "Drillo" from his dribbling skills and technical ability.

[12] However, the Iraqi football president vowed not to give up on his signature and on 17 September, Olsen signed a three-year contract.

He had tried to contact them by several means, but received the message when a new manager was installed, this action on the Iraqis part was very unexpected and their reason was said to be that they did not believe Olsen was strict enough.

On 14 January 2009, it was announced that Olsen would once again manage the Norway national team in an interim period until a successor for Åge Hareide could be found.

[16] On 27 September 2013, Olsen agreed to stand down as coach following the World Cup qualifying at home defeat to Switzerland.

[17] Olsen has at times been referred to as a "football professor" for his scientific approach to the game, an early user of video analysis of matches.

He found that breakaways played an important role to making goals, and that quick counter-attacks caught opponents off guard to organize defense.

Olsen believes that getting the ball down the field through the air to the attackers or flank players gave less chance for losing control.
