CELTIC kicked off pre-season with a 3-1 win over Sheffield Wednesday in Wales.

The Ange Postecoglou era began with the comeback win over the League One side, in a match played over three thirty minute periods.

The Hoops did first fall behind to a strike from ex-Rangers ace Josh Windass, but goals from Albian Ajeti, Owen Moffat and Odsonne Edouard ensured new boss Postecoglou tasted victory on his dugout debut.
