Video: Watch new Celtic boss Ronnie Deila doing press-ups in his underwear after victory
Celtic's new manager is certainly a colourful character.
Ronny Deila, who was appointed Celtic boss this morning on a 12-month rolling contract, celebrated a famous victory for Stromsgodset in 2009 by stripping down to his underwear(video below).
Deila has drawn comparisons in recent seasons with Jurgen Klopp, the often eccentric but highly successful Borussia Dortmund manager whose own football philosophy has earned so many admirers.
The 38-year-old, a qualified teacher, has worked uncomplainingly on a limited budget at Stromsgodset, recruiting shrewdly and combining youth with a few more experienced professionals.
