Celtic forward Leigh Griffiths says that the club's success this season solely depends on their Champions League qualification.

The Hoops have travelled to Kazakhstan to take on champions Astana in the first leg of their Champions League qualifier on Wednesday.

He said: "It makes or breaks our season if we get to the Champions League.

"Last year it set us up on a great platform. We knew it was a difficult group but having Champions League football back at Celtic Park after two disappointing years previously was massive for everybody involved.

"If we can get back into the group it will put everyone on a real high. The fans will be shouting from the rooftops and it will make the start we've made to the season worthwhile."
