Neil Lennon was appointed Celtic manager on Wednesday after nearly 10 years with the Scottish club as a player and member of its coaching staff.
The 38-year-old former Northern Ireland international's task will be to take Celtic back to the top of Scottish football after its archrival Rangers won a second consecutive league title this year.
``What I want to bring is the thunder back. I want this place rocking again,'' Lennon told a news conference. ``I want the passion, I want the noise. I want the fans to be able to walk to the ground ready for the players to go to war every time they go on the pitch.
``We've got to put up a really stronger challenge to Rangers and try to wrest the title away from them.''
Lennon joined Celtic as a midfielder in December 2000 and left seven years later for short spells with Nottingham Forest and Wycombe Wanderers before returning in a coaching capacity in 2008.
He had been Celtic's interim manager since Tony Mowbray left in April of this year and was widely expected to take over the top job full-time.
